我还尝试更改工作区设置下的 python 路径，如下所示这个答案 https://stackoverflow.com/a/54107016/11901732. with C:\Users\xxxx\AppData\Local\Microsoft\WindowsApps\python.exe这是我在命令提示符中找到的 python 路径where python但没有用。

然后我尝试了

python -m venv .venv

返回的

(.venv) PS C:\Users\xxxx\hello> python -m venv .venv

Error: [Errno 13] Permission denied: 'C:\\Users\\xxxx\\hello\\.venv\\Scripts\\python.exe'

Update:

Tried

python3.8.5 -m pip install pandas

并返回

(.venv) PS C:\Users\xxxx\hello> python3.8.5 -m pip install pandas

python3.8.5 : The term 'python3.8.5' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
