Python文件写入内容如下：
import pyautogui
import cv2打包 目标.exe:pyinstaller -F 目标.py
运行 目标.exe ,报错:
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. [6040] Failed to execute script 'test' due to unhandled exception!在windows中，cmd命令进入DOS界面：
pip list | findstr opencv
opencv-contrib-python 4.8.0.74
opencv-python 4.9.0.80 opencv-python-headless 4.7.0.72
多次折腾后，发现直接运行py文件时没问题的，但如果要成功运行打包后的exe，只能安装一个opencv版本。如果要import pyautogui,则只能安装opencv-contrib-python 4.8.0.74 。
其余版本要删除。
pip uninstall opencv-python
pip uninstall opencv-python-headless
