我在进行捆绑安装时遇到了这个错误

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing pg (0.17.1), and Bundler cannot
continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

然后我尝试了

sudo gem install pg -v '0.17.1'

并收到此错误消息

我不知道这是否与我的rails路径有关。因为我的python有一个路径问题，所有模块都无法正确安装，然后我使用virtualenv for python。红宝石有没有像virtualenv这样的东西？有谁知道如何修理它？我是Ruby on Rails的新手，谢谢：）
