提示如何删除前导破折号错误安装的软件包:“-pkgname" [英] pip how to remove incorrectly installed package with a leading dash: "-pkgname"

问题描述

键入pip freeze我在列表顶部注意到以下警告:

typing pip freeze I noticed the following warning on top of the list:

警告:无法解析要求:-atplotlib

WARNING: Could not parse requirement: -atplotlib

因此，我使用以下命令检查了已安装的软件包:pip list 而且，实际上以下内容被认为是一个软件包:

So I checked the installed packages using: pip list And, indeed the following is considered a package:

    Package         Version
    --------------- -------
    -atplotlib      3.0.3

我假设我在安装/升级matplotlib时可能遇到了错字，导致安装了上述软件包".

I assume I probably had a typo when installing/upgrading matplotlib, which led to the aformentioned "package" being installed.

很遗憾，我无法在输入时将其删除

Unfortunately I am not able to remove it as typing

pip uninstall -atplotlib

作为命令读取，并返回以下错误:no such option: -a. 对如何进行有任何建议吗?

is read as a command and returns the following error:no such option: -a. Any suggestion on how to proceed?

我找到了以下文件夹:

C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \〜atplotlib

C:\Users\name\Anaconda3\Lib\site-packages\~atplotlib

C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \〜atplotlib-3.0.3-py3.7.egg-info

C:\Users\name\Anaconda3\Lib\site-packages\~atplotlib-3.0.3-py3.7.egg-info

删除它们是否安全(足够)?

Is it safe (and sufficient) to remove them?

推荐答案

搜索损坏的程序包的名称(不带前划线)使我能够找到以下两个文件夹:

Searching for the name of the broken package (without the leading dash) allowed me to find the following two folders:

C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \〜atplotlib

C:\Users\name\Anaconda3\Lib\site-packages\~atplotlib

C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \〜atplotlib-3.0.3-py3.7.egg-info

C:\Users\name\Anaconda3\Lib\site-packages\~atplotlib-3.0.3-py3.7.egg-info

跟随Hoefling的评论(如下)

Following Hoefling's comment (below)

我检查了egg-info目录%dir%/~atplotlib-3.0.3-py3.7.egg-info/SOURCES.txt中的SOURCES.txt文件.浏览了此文件中的路径列表，并确保列出的所有路径都不包含~.然后，我将目录~atplotlib-3.0.3-py3.7.egg-info重命名为atplotlib-3.0.3-py3.7.egg-info(删除了波浪号~).
最后，我运行了pip uninstall atplotlib，它提示了以下内容:

I checked the SOURCES.txt file in the egg-info directory %dir%/~atplotlib-3.0.3-py3.7.egg-info/SOURCES.txt. Went through the list of paths in this file and made sure all paths listed did not contained ~. Then I renamed the directory ~atplotlib-3.0.3-py3.7.egg-info into atplotlib-3.0.3-py3.7.egg-info (removed the tilde ~).
Finally, I ran pip uninstall atplotlib, which prompted the following:

卸载atplotlib-3.0.3:
将删除:
C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \ atplotlib-3.0.3-py3.7.egg-info C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \ matplotlib
C:\ Users \ name \ Anaconda3 \ Lib \ site-packages \ pylab.py

Uninstalling atplotlib-3.0.3:
Would remove:
C:\Users\name\Anaconda3\Lib\site-packages\atplotlib-3.0.3-py3.7.egg-info C:\Users\name\Anaconda3\Lib\site-packages\matplotlib
C:\Users\name\Anaconda3\Lib\site-packages\pylab.py

继续执行删除操作已解决了该问题(警告消失了，并且该软件包不再位于软件包列表中.

Proceeding with the removal solved the issue (the warning disappeared and the package is not anymore on the package list.
