【问题描述】：
我正在尝试在 Ruby on Rails 中构建我的第一个应用程序，但是当我运行 bundle install 时，我收到了以下消息：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing nokogiri (1.6.6.2), and Bundler
cannot continue. Make sure that `gem install nokogiri -v '1.6.6.2'`
succeeds before bundling.
我尝试使用以下方法安装 Nokogiri：
gem install nokogiri -v 1.6.6.2
但收到此消息：
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /var/lib/gems/2.1.0 directory.
我也试过跑：
sudo gem install nokogiri -v 1.6.6.2
但收到此消息：
Building native extensions. This could take a while... ERROR: Error

我是 Ubuntu 和 Ruby on Rails 的新手。我该如何解决这些问题？
