Python urllib2 install windows

A common error you may encounter when using Python is modulenotfounderror: no module named ‘urllib2’.

This error occurs when the Python interpreter cannot detect the urllib2 library in your current environment.

The urllib2 module is split across several submodules in Python 3. The package to install is urllib3, not urllib2.

This tutorial goes through the exact steps to troubleshoot this error for the Windows, Mac and Linux operating systems.

ModuleNotFoundError: no module named ‘urllib2’

What is UrlLib?

The package urllib is a URL handling module for Python. The package contains several modules for working with URLs:

• urllib.request for opening and reading URLs
• urllib.error containing the exceptions raised by urllib.request
• urllib.parse for parsing URLs
• urllib.robotparser for passing robots.txt files

In Python 3, when importing the modules, you will find them under urllib, not urllib2.

The simplest way to install urllib is to use the package manager for Python called pip. The following installation instructions are for the major Python version 3. The package to install is urllib3, not urllib2.

How to Install urllib on Windows Operating System

First, you need to download and install Python on your PC. Ensure you select the install launcher for all users and Add Python to PATH checkboxes. The latter ensures the interpreter is in the execution path. Pip is automatically on Windows for Python versions 2.7.9+ and 3.4+.

You can check your Python version with the following command:

python3 --version

You can install pip on Windows by downloading the installation package, opening the command line and launching the installer. You can install pip via the CMD prompt by running the following command.

python get-pip.py

You may need to run the command prompt as administrator. Check whether the installation has been successful by typing.

pip --version

urllib installation on Windows Using pip

To install urllib, run the following command from the command prompt.

pip3 install urllib3

How to Install urllib on Mac Operating System using pip

Open a terminal by pressing command (⌘) + Space Bar to open the Spotlight search. Type in terminal and press enter. To get pip, first ensure you have installed Python3:

python3 --version

Python 3.8.8

Download pip by running the following curl command:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

The curl command allows you to specify a direct download link. Using the -o option sets the name of the downloaded file.

Install pip by running:

python3 get-pip.py

From the terminal, use pip3 to install urllib:

pip3 install urllib3

How to Install urllib on Linux Operating Systems

All major Linux distributions have Python installed by default. However, you will need to install pip. You can install pip from the terminal, but the installation instructions depend on the Linux distribution you are using. You will need root privileges to install pip. Open a terminal and use the commands relevant to your Linux distribution to install pip.

Installing pip for Ubuntu, Debian, and Linux Mint

sudo apt install python-pip3

Installing pip for CentOS 8 (and newer), Fedora, and Red Hat

sudo dnf install python-pip3

Installing pip for CentOS 6 and 7, and older versions of Red Hat

sudo yum install epel-release
sudo yum install python-pip3

Installing pip for Arch Linux and Manjaro

sudo pacman -S python-pip

Installing pip for OpenSUSE

sudo zypper python3-pip

urllib installation on Linux with Pip

Once you have installed pip, you can install urllib using:

pip3 install urllib3

Installing urllib Using Anaconda

First, to create a conda environment to install urllib.

conda create -n urllib python=3.6 

Then activate the urllib container. You will see “urllib” in parentheses next to the command line prompt.

source activate urllib

Now you’re ready to install urllib3 using conda.

Anaconda is a distribution of Python and R for scientific computing and data science. You can install Anaconda by going to the installation instructions. Once you have installed Anaconda and created your conda environment, you can install urllib3 using one of the following commands:

conda install -c anaconda urllib3

Check urllib Version

Once you have successfully installed urllib, you can check the version of urllib. If you used pip to install urllib, you can use pip show from your terminal.

pip show urllib3

Name: urllib3
Version: 1.26.4

AttributeError: module ‘urllib’ has no attribute ‘__version__’

You cannot get the __version__ attribute of urllib in Python 3. The urllib library in Python 3 is split into several modules. You can get the __version__ attribute of the modules under urllib, for example, request:

import urllib.request
print(urllib.request.__version__)

3.10

If you used conda to install urllib3, you can check the version using the following command within your conda environment:

conda list -f urllib3

# Name                    Version                   Build  Channel
urllib3                   1.25.11                    py_0    anaconda

Testing urllib

Once you have urllib installed, you can test the modules, for example:

from urllib.request import urlopen
with urlopen("http://www.google.com") as response:
   html = response.read()
   print(html)

Summary

Congratulations on reading to the end of this tutorial. The modulenotfounderror occurs if you misspell the module name, incorrectly point to the module path or do not have the module installed in your Python environment. If you do not have the module installed in your Python environment, you can use pip to install the package. However, you must ensure you have pip installed on your system. You can also install Anaconda on your system and use the conda install command to install urllib.

Open a Python interpreter or create a new Python script, and import the urllib2 module:

import urllib2

If you don’t receive any errors, then urllib2 has been installed successfully. Congratulations!

Conclusion

In this blog post, we have covered the step-by-step process of installing urllib2 using pip. We started by installing pip itself, then verified the installation. Next, we installed urllib2 using pip and verified its installation. We have also seen the importance of using urllib2 for various tasks, such as web scraping and interacting with APIs.

Now that you have successfully installed urllib2, we encourage you to explore its functionalities and start using it in your own Python projects. Whether you need to retrieve data from a web server or interact with APIs, urllib2 will prove to be an invaluable tool in your toolkit.

Thank you for reading this blog post, and we hope it has been helpful in your journey to become a Python developer. Happy coding!

No module named ‘urllib2’ error can be solved simply by using adequate urllib.request. This error no module named ‘urllib2’ occurs more commonly in Python3 and is easily solvable. The error occurs due to the use of a wrong call.

In this article, we take you through the error and its possible resolution, we also aim to explain the function of urllib in Python for your enhanced understanding.

The error named urllib occurs is an error specific to Python3 because the new version has some updates and changes that affect the codes and the commands used. Simply put, urllib2 is a module made for Python2, when you render it in Python2, it results in this error.

A module in Python is a folder containing the commands, definitions, and statements relating to python. A module is a very useful tool and can aid in quick working in Python. There are two types of modules in Python namely the built-in modules and the user-defined modules. While we have countless ways to go about the codes and commands, some commands are specific and cannot be meddled with.

In Python, the module named urllib is already given so it is a built-in module. Like all the other modules this module can be called and if you are attempting to call it as before, you might encounter a problem in Python3. Before we get into the error, we must first learn what urllib is and what importance it has in Python.

– Incorrect Use of Urllib2 In Calling Urllib Module in Python

According to the error line, it prompts us that there is no module named urllib2 when given the call to open urllib. It is actually a very simple error line with clear instructions but why does this happen in Python3 and not in Python2? If you call urllib2 in Python2 your desired module will be opened in no time.

Картинка с сайта: www.positioniseverything.net

There are mainly three reasons that your command line is rendering an error:

1. You are using an incorrect import statement that will surely give an error i.e. import urllib2
2. You are naming your module something it is not e.g. urllib2.py
3. You are associating a variable to your desired module

The second and the third reason for prompting an error will shadow the actual module and give an error. While all three reasons are based on human errors, it is also important here to notice that the new update of Python to Python3 has brought some major changes in the language. These changes can also be the cause of distress.

The function of urlopeon if called by import urllib2 will work just fine in Python2 as discussed earlier, only in Python3, would there be a change and an error if the change is not implemented. In the following section, we will work on the resolution of the error.

How to Resolve the Error: No Module Named ‘urllib2’ in Python?

You can resolve the error: no module named ‘urllib2’ is by using the correct command which is the use of urllib.request or urllib.responce. It’s because, in the upgrade to Python3, the module urllib and its call has been upgraded too.

Now in Python3, to call the module urllib the following command line should be used:

This simple addition will open your weblink in a Python environment with no problem and is urllib2.request equivalent in python 3. If you are struggling to find what version of Python is running on your setup, use the following command line:

This will give you the version currently installed on your computer. If it is Python3 then use urllib.request openly if it’s Python2, urllib2 should work just fine. If you wish to degrade or upgrade your Python to any version, go to your virtual environment and change it. The following lines of code will help you:

– Add Correct Commands

The newer version of Python has some very interesting additions. The use of the parent command with additional keywords, adds more functionality to it. Like the command of urllib.request, when used with additional keywords. Following are some examples:

Картинка с сайта: www.positioniseverything.net

• request.install_opener
• request.build_opener
• request.getproxies
• request.pathname2url
• request.url2pathname

All these commands can be used to perform different tasks in your virtual environment according to your needs. Be aware that some of these code lines require additional packages already installed on your computer.

In case of no module named ‘urllib2’ install the second version of Python and it should work. However, the above additions might not work. Also, urllib2 Python3 install is two combinations that will give an error. With the right version and import statement, there is no way that import urllib2 could not be resolved.

– Use Relevant Urllib

Python introduced the urllib module to import URLs in a virtual environment. To date, three different modules of the same nature and under the same name have been seen namely urllib (the original module), urllib2 (the better version of the original), and lastly, urllib3 (the current and the most fulfilling urllib module in Python). The error may occur while importing any of the three libraries but the most recurrent errors will be regarding urllib2 and urllib3.

Картинка с сайта: www.positioniseverything.net

Urllib was the most primitive module introduced in Python for importing data from an URL. It was simple and worked on Python 1 and its associated versions. Urllib2 as mentioned above was the second version of the original one and worked on Python2 and some later versions of Python or Python1 as well. Lastly, Urllib3 was given in Python3 with some major upgrades.

The basic function of this module is simple which is importing URLs but the newer version added much more complexity in terms of use to the module. They work best on their corresponding versions of Python. Urllib3 is the latest among the group and has got the best deal to offer.

FAQ

1. What Is the Role of Urllib in the No Module Named ‘URLLIB2’ Error?

The urllib module in Python defines and directs classes and functions that help in opening URLs. This module will help in opening URLs that are mostly HTTP with the given redirections, cookies, and/or authentications. The role of this module significantly differs between different versions of Python.

In Python2, using the call urllib alone would open the module and lets you in on all the functions but not in Python3.

While working in Python, on any project, we need to fetch data from a source which may be a website. Given the environment of Python, it is important that the source, which may be another environment or an URL, may also be opened in a Python environment, and from there the contents are copied and pasted. This is why URLs are sometimes opened in Python and for doing so the call urllib was heavily used.

2. How to install Urllib request in Python3?

In Python3, you can install urllib by using pip if it is not already present in your virtual environment. Simply write pip install urllib2 or urllib3 and the newest version should be installed. You can use urllib.request to make any URL request of your choice.

Make sure to use the correct urllib.request for your version of Python, either 2 or 3 and you can get more information by searching: urllib2 pypi.

3. In Python2, How To Use Urllib2?

You can use urllib2 in Python2 just by adding the URL to urlopen() and get the related data. Urllib in Python2 has one of the easiest interfaces and the function urlopeon. First of all import the urllib2 module in Python2.

Secondly, type the required URL in the response which will then become a file-like object and convert the data from the function into a string (HTML).

Conclusions

We have covered a lot of ground regarding the urllib function in Python and the consequent error in Python3. Python may not be as easy to work with as it is for some people but some diligent tinkering with the commands can make your life easier. For your convenience, we have gathered all of the key points discussed in the article below:

• The error no module named ‘urllib2’ exists in the virtual environment of Python3 where to import URL, the call urllib2 does not work.
• This error occurs because, in the updated version of Python, the call urllib has been broken down to urllib.request, and using this call will sort your problem out.
• The function of urllib is used to import data from URLs in the virtual environment.
• This urllib module can easily be installed in your computer by pip depending on what version of Python you have or require.

Just like that the error is resolved and now you can open URLs in your virtual environment with ease.

In Python, urllib is a built-in library that helps users in fetching URLs (Uniform Resource Locators).

Using this library, various tasks such as fetching URLs, using HTTP protocol, email protocols, etc. can be done effortlessly. In this tutorial, we will go through the steps required to install urllib in Python and how to use it for basic tasks.

Step 1: Ensure Python is installed

Since urllib is a built-in library, there is no need to specifically install it. However, it is essential to have Python installed on your system. Check the Python installation on your system by running the following command:

If Python is installed, the output should display the current Python version. If not, visit the official Python website to download and install the appropriate version for your operating system.

Step 2: Decide between urllib or urllib2

urllib and urllib2 are two different versions of the library. In Python 2.x versions, urllib2 is used, while Python 3.x versions use urllib. Depending on your Python version, you will have to import either urllib or urllib2 for your code.

Step 3: Import urllib in Python

To import urllib in Python, use the following code:

If you’re using Python 2.x, use the following code instead:

Step 4: Use urllib to fetch a URL

Now that you have the urllib module imported, you can use it to fetch URLs. Here’s an example of fetching URL content using Python:

For Python 2.x:

The urlopen() function fetches the URL content and returns it in bytes for Python 3.x, or as a string for Python 2.x. The content must then be decoded into a string (for Python 3.x).

Complete Example:

Output:

<!doctype html>
<html>
<head>
    <title>Example Domain</title>

    <meta charset="utf-8" />
    <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />

...

Conclusion

In this tutorial, we covered how to install urllib in Python and use it to fetch a URL. Since urllib is a built-in library, it does not require any external installation.

All you need to do is make sure Python is installed and import the urllib (or urllib2) module in your code. With urllib, you can further explore additional features like URL parsing, error handling, and more.
