Why can't I install matplotlib or pandas with pip OR miniconda?-CodePudding

Windows 10 Python 3.1

I have a script written that requires pandas and matplotlib. However, I'm having trouble installing either even though I've tried both pip in cmd and conda in Miniconda.

Here's the error I get when trying to install either via pip in cmd (ie py -m pip install -U matplotlib:

ERROR: Command errored out with exit status 1:

I'm really not sure what could be wrong since I didn't run into these problems when I installed these packages through similar means on my other PC, and I definitely do have Python 3.1 installed. Any help would be appreciated, thanks!

CodePudding user response：

Try creating a new environment and installing matplotlib and numpy in it directly as follows:

conda create --new env_nick python=3.8 numpy matplotlib

Then, activate the environment as

conda activate env_nick

Your python version is old and incompatible with some of the updated packages.
