An error occured while installing nokogiri (1.5.0), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.0'` succeeds before bundling.
You can skip this part. The error message is pretty much self explanatory, but the website requires a few more words explaining the code.
你可以跳过这部分。错误消息几乎不言自明，但该网站需要更多的文字来解释代码。
Any thoughts?
有什么想法吗？
