问题描述，程序中含有cv2库，使用pyinstaller打包成exe后，执行出现闪退，并且报错没导入cv2库，百度得知是cv2版本太高

报错代码： 

raise ImportError('ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.')
ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.
[15648] Failed to execute script '调用摄像头' due to unhandled exception!


 

raise ImportError('ERROR: recursion is detected during loading of "cv2" bina

执行下列操作，重新安装低版本cv2后，问题解决

pip uninstall opencv-python
pip install opencv-python==4.5.1.48


 Python程序打包成exe

pip install pyinstaller #安装打包程序
pyinstaller -F 要打包的python程序


 重新打包后程序正常执行
