无法卸载名为`-umpy`的软件包 [英] Unable to uninstall package named `-umpy`

问题描述

Runnig py -m pip list会产生:

Runnig py -m pip list in windows powershell, produces:

Package         Version
--------------- -------
-umpy           1.15.4
autogui         0.1.8
beautifulsoup4  4.8.0
cycler          0.10.0
et-xmlfile      1.0.1
...and so on

如您所见，有一个名为-umpy的软件包，它必须是某种计算机打.

as you can see there is a package named -umpy which must be some kind of a computer hiccup.

现在我想卸载该软件包，但是py -m pip uninstall -umpy命令不起作用，因为它认为我正在尝试传递参数.

Now I want to uninstall this package but the py -m pip uninstall -umpy command does not work since it thinks I am trying to pass an argument..

有人知道如何摆脱此软件包吗?

我已经尝试过各种逃生方法:

I have already tried various escapes:

>> py -m pip uninstall /-umpy
ERROR: Invalid requirement: '/-umpy'

>> py -m pip uninstall `-umpy
Usage:
  C:\Program Files\Python35\python.exe -m pip uninstall [options] <package> ...
  C:\Program Files\Python35\python.exe -m pip uninstall [options] -r <requirements file> ...

no such option: -u

>> py -m pip uninstall \-umpy
ERROR: Invalid requirement: '\\-umpy'
Hint: It looks like a path. File '\-umpy' does not exist.

>> py -m pip uninstall "-umpy"
Usage:
  C:\Program Files\Python35\python.exe -m pip uninstall [options] <package> ...
  C:\Program Files\Python35\python.exe -m pip uninstall [options] -r <requirements file> ...

no such option: -u

推荐答案

尝试

py -m pip uninstall -- -umpy

双破折号将选项与非选项分开；完全是这样用的.

Double dashes separate options from non-options; used exactly in case like this.

顺便说一句，我认为-umpy不是真正的软件包.看来这是由于软件包numpy卸载失败而遗留下来的.

BTW, I don't think -umpy is a real package. It seems it's a leftover from an unsuccessful uninstallation of a package numpy.

可能是您需要手动删除其目录.为此，请键入py -m pip list -v以获得所有已安装模块及其安装位置的列表，然后只需删除相应的文件夹即可.

It could be you need to remove its directories manually. To do that, type py -m pip list -v to get a list of all installed modules together with their installation location and then simply delete the corresponding folders.
