python安装失败无法访问_错误：由于环境错误而无法安装包错误：[WinError 5]访问被拒绝：...

我试图使用python -m pip install opencv-python -U pip --user将opencv python安装到windows10中的visualstudio代码中，但总是收到错误。希望有人能帮我改正错误。在

我尝试了不同的建议，比如将--user放在命令行的末尾PS C:\Users\user\Desktop\sample> python -m pip --no-cache-dir install opencv-python -U pip --user
