在 VS 上无法进行 pipenv install --python3.9，显示异常

Question

I'm a python beginner. I'm using Visual Studio Code (edited) and used to be able to do pipenv install --python3.9 in the terminal, but now after I've done a lot of installation and stuff (by following different tutorials, trying out different stuff), I'm getting tons of exceptions:

During handling of the above exception, another exception occurred:

and it just goes on.

you can trying making a virtual env with
python3 -m venv venv
activate the virtual environment with
