在 OS X 上安装 python 库

Question

当我在 OS X yosemite 上的终端 'sudo pip install scipy'（实际上使用任何 python 包，如 numpy、pandas ..）上运行命令时，我收到以下错误。

Collecting scipy

我的 'git clone ..' 工作得很好（我安装了 home brew）。我在代理后面，我已经做了别名。

专门为pip指定代理，

sudo pip --proxy http://user:pass@proxy.server:port install packagename

pip 不使用 http_proxy 变量，在 OS X 终端中设置。
