如标题，使用python3.6根据网页博客编写自动下载图片脚本时遇到的相似问题，需要升级第三方库，但是无法卸载，报错类似如下（软件包可能不同，对于相似问题可尝试使用同样方法处理）
Cannot uninstall 'html5lib'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
问题解决：请找到python下面的路径
然后再找到这个文件把它删除就可以了
类似的，以后这种问题的解决方式都可以这样入手。
可能的原因，可能之前的第三方库是通过离线文件方式安装的， 删除相应的egg-info后可以尝试解决。

I'm on El Capitan and I want to install numpy with pip. However I get the following error:
Detected a distutils installed project ('numpy') which we cannot uninstall. The metadata provided by distutils does not
contain a list of files which have been installed, so pip does not know which files to uninstall.The existing numpy version seems to be 1.10.4 and the one I try to install is 1.9.2, but I need it. Is there a way to uninstall this version with distutils? Or at least any way to tell pip that there is numpy installed?
Answers
Since there is no metadata about the installed files, I found the easiest way to be removing the files manually. Simply retrieve the directory of the module (I referred to this: Retrieving python module path), and delete the folder, as well as the accomp anying .egg-info file. Then install your desired numpy version without the --update flag.
