【问题描述】：
我是 Mac OS X 的新手。我想建立一个 Python 编程环境。 我使用pip 来管理第三方包。
我使用 easy_install 安装了 pip。
sudo easy_install pip
我尝试将 pip 从 6.1.0 升级到 6.1.1。但是，我的请求被拒绝了，我收到了以下消息。
$ pip install --upgrade pip
You are using pip version 6.1.0, however version 6.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting pip
Using cached pip-6.1.1-py2.py3-none-any.whl
Installing collected packages: pip
Found existing installation: pip 6.1.0
Uninstalling pip-6.1.0:
Successfully uninstalled pip-6.1.0

看来我没有升级pip的权限。我认为这不是缺少依赖包的问题。我使用的 OS X 系统是 OS X 10.10.3。我正在使用 Python 2.7.9。
有人可以帮我解决这个问题吗？

使用
sudo运行它。
