Hello.
I’m facing difficulty to use PyPlot on my windows 10 machine.
The versions I’m using are: Julia v1.3.0; Conda v1.3.0; PyCall v1.91.2; PyPlot v2.8.2. I already installed the latest matlibplot via Conda.update(), and it’s v3.1.1 now. Also, the python executable used by PyCall seems to be correctly specified:
julia> using PyCall
julia> PyCall.python
"C:\\Users\\xxx\\.julia\\conda\\3\\python.exe"
Then, I got the following errors. Essentially, PyPlot keeps trying to install matplotlib even though it was already installed. In fact, the warnings below say «All requested packages already installed.» Yet, each time when I try to use PyPlot, this happens and I cannot use it on windows. It works under macOS though. I would greatly appreciate it if someone could tell me what to do.
Thanks!

Sorry, did not see this question until this morning— I was able to reproduce your problem!!
The short answer is don’t install this specific version of matplotlib with the version of Python you have, but install the most current version from the repository that matches up with the Python you are using. Matplotlib 3.1.3 (and its dependencies) should be fully compatible with Python 3.8.3 on Windows 10.
PS C:\Users\jeff> .\testenv\Scripts\activate (testenv) PS C:\Users\jeff> pip install matplotlib
MatplotLib has a huge number of dependecies and specific version of tools, so you would have to uninstall the current version of Python «setuptools» library and install an earlier version of setuptools that matches to matplotlib 2.2.2.
Too much work, in my opinion!
BELOW, I reproduced your error. In a «pristine» virtual environment of Python 3.8

Excellent! Good to know. I suppose I should have suspected as much, compatibility-wise. I wanted to be sure there wasn’t some bigger issue I needed to be aware of. Thanks for your help!

Hello, if you have come across this post then definitely you are curious to know the facts:
- Why your terminal is taking too much time to execute the installation and why the terminal is not responding after showing this message “
Running setup.py install for matplotlib ... /“? - Another question might arise. Should I wait or close the terminal and give it another try.
So I am here to clear all of your doubts.
What to do after seeing this message for longer than usual “Running setup.py install for matplotlib … \”
After running this command pip3 install matplotlib or pip install matplotlibyou may face this type of situation:
But do not worry at this stage if it’s taking longer than usual time.
What I did was:
- Closed the terminal just thinking that I will retry. (But still waiting time was longer)
- Then I searched over the internet and someone suggested upgrading these:
pip3 install --upgrade pip(for python3 or simply use pip instead of pip3 if you are using Python 2) andpip install --upgrade setuptools.
I suggest you do not do these as these will not harm anything but no need to do these.
You are not getting any type of error, it’s just a delay for the system configuration.
Just wait for 5 minutes hardly. It will be installed fine.
After waiting for few times I got this result:
I know that this answer might be weird for some people. But I thought I should share this with people like me who faced the same issue.
Купил новый компьютер с Windows 10, материнская плата Asus, процессор Ryzen 3200 Vega, и тут началась пляска с бубнами:
— Установил Python 3.8.6 успешно
— Установил matplotlib через pip успешно
— При попытке кодинга с помощью этого плагина выходит следующая ошибка:

Any idea how to solve this? Thanks.
