python - easy_install pip == [Errno 8] 提供的节 pip 名或服务名，或未知

Question

我在为通过 pythonbrew 安装的 python 2.7.3 安装 pip 时遇到问题:

pythonbrew update --master
pythonbrew install 2.7.3 --force

当试图从 pip.openplans.org 获取 pip 时，这在最后阶段挂起时失败了:

Installed /Users/andrei/.pythonbrew/pythons/Python-2.7.3/lib/python2.7/site-packages/distribute-0.6.28-py2.7.egg

运行 easy_install pip 也会导致同样的错误。当然，我仍然可以克隆 pip 存储库并手动安装它，但很高兴知道为什么它会通过 easy_install 失败。有什么想法吗？

更新:

$ host pip.openplans.org
pip.openplans.org is an alias for puffin.oddbird.net.
puffin.oddbird.net has address 173.203.85.138

我遇到了类似的问题；该命令在 iTerm2 中失败，但在默认的 OS X 终端中没有。重启 iTerm2 解决了这个问题。
