Question

我是Mac OS X的新手。我想为python编程设置一个环境。我正在使用pip来管理第三方软件包。

我用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，我得到了以下消息。

$ 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.

似乎我没有权限升级pip。我认为这不是缺乏依赖包的问题。我正在使用的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？

您使用sudo easy_install pip安装了它，这使得root用户创建了pip。

升级时，您还应该使用：

sudo pip install --upgrade pip

升级权限被拒绝：如何在Mac OS X上升级pip？
