PYQT报错，Available platform plugins are: xcb, eglfs, linuxfb, minimal, minimalegl, of…..

命令行运行下述命令即可。

pip install opencv_python_headless

 

 

无效方式：

网上公开很多添加环境变量的方式，经实验基本都无效，比如下面这个

envpath = '/data/xx/xx/venv/lib/python3.6/site-packages/cv2/qt/plugins/platforms'
os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = envpath
