opencv-python安装不了，因为我没有vs？
[英]I can't install opencv-python because I don't have vs?
问题描述
每当我尝试 pip 安装 opencv-python 时，都会出现一个错误，提示我需要安装 visual studio 2022，但我已经安装了它。 我完全不知道如何解决这个问题，现在真的需要 opencv 才能在我的设备上工作。
我也尝试过使用 opencv-contrib-python 但这给了我同样的错误。 错误信息是：
ERROR: Command errored out with exit status 1:
command: 'c:\program files\python38\python.exe' 'c:\program files\python38\lib\site-packages\pip\_vendor\pep517\_in_process.py' build_wheel 'C:\Users\NOAH~1.ROB\AppData\Local\Temp\tmpb6spxf7z'
