OpenCV经常提醒环境变量“Path中有一些路径包涵“；”字符

提示：

The environment variable 'Path' seems to have some paths containing the '"' character. The existence of such a character is known to have caused the Python extension to not load. If the extension fails to load please modify your paths to remove this '"' character.

翻译：

环境变量“Path”似乎有一些路径包含“；”字符。已知存在此类字符导致Python扩展无法加载。如果扩展无法加载，请修改路径以删除此“；”字符。

解决方法：

去环境变量“Patn”中，把”；“删除即可。

建议：删除之前，可以先拍张照片或者截图，防止出现其他问题。
