You can install it through Homebrew on OS X. Why would you install Python with Homebrew? 您可以在OS X上通过Homebrew安装它。为什么要在Homebrew中安装Python？
The version of Python that ships with OS X is great for learning but it's not good for development. OS X附带的Python版本非常适合学习，但不利于开发。 The version shipped with OS X may be out of date from the official current Python release, which is considered the stable production version. OS X附带的版本可能已从官方的当前Python发行版过时了，该版本被认为是稳定的生产版本。 ( source ) （ 来源 ）

The simplest solution is to follow the installation instruction from pip's home site . 最简单的解决方案是按照pip主页上的安装说明进行操作 。
Basically, this consists in: 基本上，这包括：
- downloading get-pip.py . 下载get-pip.py 。 Be sure to do this by following a trusted link since you will have to run the script as root. 确保通过遵循受信任的链接来执行此操作，因为您将必须以root用户身份运行脚本。
- call
sudo python get-pip.py调用sudo python get-pip.py
The main advantage of that solution is that it install pip for the python version that has been used to run get-pip.py , which means that if you use the default OS X installation of python to run get-pip.py you will install pip for the python install from the system. 该解决方案的主要优点是，它为用于运行get-pip.py的python版本安装pip，这意味着，如果您使用默认的OS X安装python来运行get-pip.py ，则将安装从系统安装python的pip。
Most solutions that use a package manager (homebrew or macport) on OS X create a redundant installation of python in the environment of the package manager which can create inconsistencies in your system since, depending on what you are doing, you may call one installation of python instead of another. 大多数在OS X上使用软件包管理器（自制或Macport）的解决方案都会在软件包管理器的环境中创建python的冗余安装，这可能会在系统中造成不一致，因为根据您所执行的操作，您可以将安装称为python，而不是另一个。
