Answer 1

这似乎是因为在OSX操作系统中自带的Python默认版本在某些地方需要管理员权限才能运行。

一般来说，你可能不应该使用操作系统自带的Python进行开发，我个人也更倾向于不随便用管理员权限安装那些不明显需要根权限的东西。

与其使用默认版本，不如通过Homebrew安装一个专属于你的Python版本。

brew install python

这样你就可以免费获得正确安装的pip命令了！

Answer 2

好的！你需要管理员权限才能这样做。输入 sudo python get-pip.py 然后输入管理员密码。

这样它会自动为你安装 pip-6.1.1。

Answer 3

因为我没有50的声望，所以不能评论，我就把我的想法放在这里当作回答。

即使你是管理员，在做任何事情之前，还是得先输入 sudo 命令... 要检查你的账户是否有管理员权限，可以在终端里输入 sudo bash，如果出现 myusername is not in the sudoers file. This incident will be reported. 这样的提示，那说明你不是管理员。

下面是一个简单的演示：

bash-3.2# 
bash-3.2# exit

或者你可以把前两步合并，直接进入第三步，如果在输入 sudo 时出现错误，那你就不是管理员。
