由于环境错误，无法安装 Open-CV：[WinError 5] 访问被拒绝

Question

Whenever I run pip install opencv-python , I get

Could not install packages due to an EnvironmentError: [WinError 5] Access is denied: 'C:\\Users\\redactedusername\\AppData\\Local\\Temp\\pip-unpack-wrckbxoo\\opencv_python-4.0.0.21-cp36-cp36m-win_amd64.whl': Check the permissions.

Answer 2
