我试图通过以下方式安装python brew：

brew install python

但是得到以下错误：

Stevens-MacBook-Pro :: ~ ‹master*› » brew install python

  pip install --upgrade setuptools

You can install Python packages with
  pip install <package>

They will install into the site-package directory
  /usr/local/lib/python2.7/site-packages

错误消息说安装后失败，并尝试再次安装它：

brew postinstall python

但错误仍然存​​在。我也尝试过brew linkapps，它成功地完全链接了 python，但是当我pip从控制台运行时，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

知道可能出了什么问题吗？

Pyenv 是一个 python 版本管理工具，类似于 rbenv，但用于 python。

您可以通过 pyenv 轻松安装和更改 python 版本。

下面展示了如何通过pyenv安装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

如您所见，它非常简单。

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

我建议尝试一下pyenv！
