Question

我通过pythonbrew安装了python 2.7.3安装pip的麻烦：

pythonbrew update --master
pythonbrew install 2.7.3 --force

在尝试从pip.openplans.org获取点数时，最后阶段失败了：

运行easy_install pip也会导致同样的错误。当然，我仍然可以克隆pip repo并手动安装它，但很高兴知道它为什么会通过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

Answer 1

有两件事可能是错的：

pip.openplans.org的DNS查找失败;使用host pip.openplans.org进行测试。这可能是一个地方问题;使用host pip.openplans.org 8.8.8.8和host pip.openplans.org 8.8.4.4对Google DNS服务器进行测试。如果所有这些查找失败，请向互联网上帝牺牲一只鸡并等待改进。
如果DNS查找没有失败，但是安装是，那么您的本地DNS缓存可能会持续进行否定查找。使用命令dscacheutil -flushcache冲洗它。

Answer 2

对我来说，在Mac OS X Yosemite上再次启用和关闭WiFi。

easy_install pip == [Errno 8]提供nodename或servname，或者不知道
