无法在 Python 3.10 上安装 Matplotlib

Question

python3.10 -m pip install --user matplotlib

I keep getting the following error when I run the above to install Matplotlib. I was initially getting a C++ error and I installed Visual Studio.

Answer 1

Matplotlib doesn't support Python 3.10 at the moment, so you have the following options.

1. Downgrade to Python 3.9.
2. Install the pre-release version of Matplotlib which does support Python 3.10. This can be done with the command pip install matplotlib==3.5.0rc1 (and is what I would recommend doing).

Answer 2

I have been having the same problem for a while now. Another answer I found was here: Error trying to install matplotlib in Windows

In summary, pip install --pre matplotlib also works.
