有时候我们使用shutil.rmtree()、os.rmdir()、os.remove()删除文件时会报[WinError 5] 拒绝访问的错误： 如使用os.remove()删除当前文件夹下的'PackageCache\\com.unity.textmeshpro@1.3.0\\Tests\\Editor.meta'时提示

[WinError 5] 拒绝访问。: ‘PackageCache\com.unity.textmeshpro@1.3.0\Tests\Editor.meta’

这个时候我们可以让Python运行cmd命令强制删除此文件：

import os os.system('del "PackageCache\com.unity.textmeshpro@1.3.0\Tests\Editor.meta" /F')

关于使用CMD命令删除文件或文件夹，可以参考：Windows CMD删除文件或文件夹命令帮助
