Any suggestions would be appreciated

Answer 1

Look in to this question I am trying to install pillow using 'pip'

In short, 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 to download the pillow wheels from here and try to install it may it will work.

The following command might also help.

pip intstall pipwin
pipwin install <package name>

Answer 2

Most probably, pandas wheel is not supported in Python 3.9 version yet. If this is the situation, you can try with pipwin .

First, install pipwin with

pip install pipwin

then

pipwin install pandas .

NB: pipwin behaves just like pip

Answer 3

我一一安装了所有依赖项，然后再次尝试 pip install pandas 并且它正常工作。
