Can't install new packages for Python (Python 3.9.0, Windows 10)

python matplotlib pip package conda
32,371

Solution 1

Python 3.9 is not even released for 10 days yet. As far as i see a lot of the packages are not supporting Python 3.9 yet. I think your best bet is to uninstall Python 3.9 and install Python 3.8.6. If you want you could try the following just to make sure, but i think i won't work.

pip intstall pipwin
pipwin install <package name>

Solution 2

It's probably advisable to first go to: https://www.python.org/downloads/

and find latest security release and use it. If you scroll little bit down you see:

enter image description here

So at the time of writing this that is still Python 3.7.

And that scoll little bit more down the same page and download latest release of Python 3.7 :

enter image description here

Which at the time of writting as you can see is Python 3.7.9:

Solution 3

I had the same issue. I went back to version 3.8.6 and everything works fine. We were a little too early.

    In order to upgrade and clean up, I have reset my PC and installed Windows 10. Naturally, I installed Python as I use it frequently. But when I tried to install MatPlotLib using the command "pip install matplotlib", it shows an error message colored in red:

    It does the same for every other package I want to install. I have no idea what to do. I have already tried reinstalling pip, Python, I have tried installing the packages via conda, but I can't seem to solve the problem. Any help would be appreciated.
