pywin32的安装/卸载问题

Question

我正在尝试简单卸载/安装此软件包，并在成功卸载后出现以下错误

python -m pip uninstall pywin32
...
Successfully uninstalled pywin32-227
...
PermissionError: [WinError 5] Access is denied: 'c:\\python36\\lib\\site-packages\\~0win32_system32\\pythoncom36.dll'

我试过以下几件事：

1. 以管理员身份运行卸载
2. 将我的pip版本移动到20.0.2，因为最新版本21.0.1出现了相同的问题

我在我的Windows计算机上遇到了同样的问题

试试这个

pip install  user pywin32

另外，要升级pip

python -m pip install -U pip  user
