由于我没有50的声望，我不能评论，我将在回答中"评论"。

虽然你可能是管理员，但你仍然需要在做任何事情之前输入sudo…要检查您的帐户是否具有管理员权限，请在终端中输入sudo bash，如果显示myusername is not in the sudoers file. This incident will be reported.，则说明您不是管理员。

下面是上面的一个简短的演示:

或者您可以将前两个步骤结合起来，然后进入第三个步骤，如果在输入sudo时出现错误，那么您不是管理员。

Answer 2

给你!您需要管理员权限才能执行此操作。输入sudo python get-pip.py，输入admin密码。

它会自动为你安装pip-6.1.1

Answer 3

这似乎是因为Python的默认版本，随OSX操作系统一起发布，需要sudo权限才能在一些地方运行。

一般来说，你可能不应该使用python的操作系统版本进行开发，而且我个人更倾向于永远不要sudo安装任何明显不需要root访问权限的东西。

不使用默认版本，使用Homebrew安装用户特定的Python安装。

brew install python

然后你得到pip命令正确安装免费!
