我尝试安装pip时遇到了以下错误:
WARNING: The scripts pip.exe, pip3.8.exe and pip3.exe are installed in 'C:\Users\Itamar\AppData\Local\Programs\Python\Python38\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
这是什么意思?如何修复?
