brew後安裝python（2.7.13）：[Errno 13] Permission denied

我在OS X 10.11.6上。我今天更新和升級了brew。之後，pip沒有工作。它看起來好像在升級過程中沒有安裝它。當我完成了升級，我看到了警告：brew後安裝python（2.7.13）：[Errno 13] Permission denied

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

於是我就brew postinstall python，然後我遇到的錯誤：

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

在this後，他們說：

The post-install step did not complete successfully due to error: could not delete '/usr/local/lib/python2.7/site-packages/pip/__init__.py': Permission denied. Manually deleting that file and then running brew postinstall python again fixed it.

所以我認爲修復將是相同的，我手動刪除/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'，以便

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

我又跑brew postinstall python但現在我得到：

... 
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'`

我找到了「修復」使用easy_install安裝PIP：

sudo easy_install pip

而現在一切似乎很好地工作。不過，我有兩個問題：

我是不是已經搞亂了手動刪除'/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'？
當brew postinstall python時[Errno 13] Permission denied會修復什麼？

如果它沒有任何用處的，這裏是我的brew config和brew doctor輸出畢竟今天發生：

我發現的最簡單的方法解決這個問題是隻需將文件夾的所有權設置爲您的用戶名：

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

編輯：有時，我也運行此：

sudo -H python3 -m pip install ...

或

sudo -H pip install

那樣簡單（捂臉）。有效。非常感謝 – Javier
