pip卸载时出现PermissionError

Question

我可以安装一个包：

pip install brotli

但如果我试图删除，它会失败：

PS D:Desktop> pip uninstall -y brotli
Found existing installation: Brotli 1.0.9
Uninstalling Brotli-1.0.9:

奇怪的是，在失败后，我可以回去手动删除文件夹，没有问题：

PS D:Desktop> python.exe

Type "help", "copyright", "credits" or "license" for more information.
>>> import shutil
>>> shutil.rmtree('C:\Windows\Temp\pip-uninstall-fi5xmcvd')

我在windows 上使用python

Answer 1

问题出在Pip代码中，这里[1]:

from pip._vendor.requests.models import Request, Response

一旦进行导入，则由pip本身导入brotli文件，并且所以在pip退出之前不能删除它。这是一个pip问题，而不是brotli或任何其他包装。

Answer 2

如果有人想卸载brotli，您可以直接删除<YOUR PYTHON PATH>libsite-packages文件夹下的相关文件或文件夹。这在anaconda和普通python环境中都有效。
