Question

我在OS X 10.11.6上。我今天更新并升级了brew。之后，pip无效。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this帖子中，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。

所以我认为修复方法是一样的，我手动删除/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

我再次跑brew postinstall python，但现在我获得了：

...
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'`

我通过使用easy_install安装pip找到了“修复”：

sudo easy_install pip

现在一切似乎都运转良好。但是，我有两个问题：

我是否通过手动删除'/usr/local/lib/python2.7/site-packages/pkg_resources/__init__.py'？
[Errno 13] Permission denied时brew postinstall python的解决方法是什么？

如果它有任何用处，在今天发生的所有事情之后，这是我的brew config和brew doctor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：有时候，我也会这样做：

sudo -H python3 -m pip install ...

或

sudo -H pip install

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