brew postinstall python(2.7.13):[Errno 13]权限被拒绝

Question

我在OS X 10.11.6上.我今天更新并升级了brew.在那之后,pip没有奏效.在升级过程中看起来好像没有安装.当我完成升级后,我看到了警告:

Warning: The post-install step did not complete successfully You can try again using brew postinstall python

所以我跑了brew postinstall python,然后我遇到了错误:

error: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'

在这篇文章中他们说:

由于error: could not delete '/usr/local/lib/python2.7/site-packages/pip/__init__.py': Permission denied.手动删除该文件然后再次运行brew postinstall python,安装后步骤未成功完成.

所以我认为修复将是相同的,我手动删除/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'所以

$ ls /usr/local/lib/python2.7/site-packages/pkg_resources/
_vendor extern

我又跑brew postinstall python了,但现在我得到了:

...
copying build/lib/easy_install.py -> /usr/local/lib/python2.7/site-packages
copying build/lib/pkg_resources/__init__.py -> /usr/local/lib/python2.7/site-packages/pkg_resources
error: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'` 

我通过安装pip找到了"修复" easy_install:

sudo easy_install pip

而现在一切似乎都很好.但是,我有两个问题:

1. 我手动删除搞砸了'/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'吗？

2. 什么是什么[Errno 13] Permission denied时候修复brew postinstall python？

如果它有任何用处,这是我brew config和brew doctor今天发生的所有事后的输出:

我发现解决此问题的最简单方法是将文件夹的所有权设置为您的用户名:

chown -R `whoami` /usr/local/lib/python2.7/site-packages/

编辑:有时,我也运行:

sudo -H python3 -m pip install ... 

要么

sudo -H pip install
