我正在运行 Ubuntu 12.10，并且当我运行命令时：

bundle install

我得到：

Installing nokogiri (1.5.2) with native extensions

Gem files will remain installed in /home/site/.bundler/tmp/19240/gems/nokogiri-1.5.2 for inspection.
Results logged to /home/site/.bundler/tmp/19240/gems/nokogiri-1.5.2/ext/nokogiri/gem_make.out
An error occured while installing nokogiri (1.5.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.2'` succeeds before bundling.

当我运行时：

gem install nokogiri -v '1.5.2'

我得到：

site@ubuntu:~/Documents/shopqi$ gem install nokogiri -v '1.5.2'

没有错误，但如果我再试bundle install一次，我会收到没有安装 Nokogiri 的错误。

运行 sudo gem install nokogiri -v '1.5.2' 后 gem_make.out 的内容是：

请问有什么帮助吗？

先试试这个：

$  apt-get install libxml2-dev libxslt1-dev

此外，如果您使用的是 rvm，请执行以下操作：

$ rvm requirements

Ubuntu 12.10 采用 Debian 的强化包装器，其中包括一组导致此编译错误的 GCC 的默认标志。我们已经在 Nokogiri 1.5.4 及更高版本中解决了这个问题，因此您需要升级或找到自己的解决方法。

有关Debian 强化的信息，请参见此处。
