但是得到以下错误：

You can install Python packages with
  pip install <package>

They will install into the site-package directory

错误消息显示安装后失败，并尝试再次安装：

brew postinstall python

但错误仍然存在。我也试过brew linkapps并成功完全链接python但是当我从控制台运行pip时我得到了这个错误：

Stevens-MacBook-Pro :: ~ ‹master*› » pip
zsh: /usr/local/bin/pip: bad interpreter: @@HOMEBREW_PREFIX@@/opt/python/bin/python2.7: no such file or directory

知道可能出现什么问题吗？

Pyenv是一个python版本管理工具，类似于rbenv但是对于python。

您可以轻松地通过pyenv轻松安装和更改python版本。

以下显示如何通过pyenv：

安装带有2.7.8版本的python

ubuntu@ubuntu:~$ pyenv install 2.7.8
Downloading Python-2.7.8.tgz...
-> http://yyuu.github.io/pythons/74d70b914da4487aa1d97222b29e9554d042f825f26cb2b93abd20fdda56b557
Installing Python-2.7.8...
Installing setuptools from https://bootstrap.pypa.io/ez_setup.py...
Installing pip from https://bootstrap.pypa.io/get-pip.py...
Installed Python-2.7.8 to /home/ubuntu/.pyenv/versions/2.7.8

如你所见，非常简单。

命令pyenv install "version"可以帮助您轻松安装特定版本的python甚至是pip，setuptools也会自动安装。

我建议试试pyenv !!
