我还尝试按照此答案在工作区设置下更改python路径。使用C:\Users\xxxx\AppData\Local\Microsoft\WindowsApps\python.exe它是我在命令提示符中使用的python路径，where python但没有用。
然后我尝试
python -m venv .venv
哪个回来了
(.venv) PS C:\Users\xxxx\hello> python -m venv .venv
Error: [Errno 13] Permission denied: 'C:\\Users\\xxxx\\hello\\.venv\\Scripts\\python.exe'
更新：
试过了
python3.8.5 -m pip install pandas
然后返回
(.venv) PS C:\Users\xxxx\hello> python3.8.5 -m pip install pandas

解决方案似乎很简单！首先要紧！
通过查看您的帖子，您似乎已经遵循了安装指南Pandas。这没什么不妥，但是我必须首先根据您提供给我们的信息，您似乎正在运行Windows Powershell PS C:\Users\xxxx\hello>和the error format matches Powershell。因此，sudo不会被识别，因为sudo对于Unix-based类似Debian, Ubuntu, and so on这样的系统，admin命令是无效的命令！
但是，这是正确安装的方法：（我假设您正在运行Windows，但如果不是这样，请更正我，我会为您提供Unix版本！）
1-Windows键，搜索CMD并运行它，因为administrator这对于避免权限问题很重要！
2-运行pip3 install pandas 或 python3 -m pip3 install pandas
