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')
