Ruby 在Ubuntu 12.10上安装Nokogiri（1.5.2）时出现问题

我正在运行Ubuntu 12.10，当我运行命令时：

bundle install

我得到：

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.

当我跑步时：

gem install nokogiri -v '1.5.2'

我得到：

没有错误，但是如果我再次尝试

bundle安装

，我会得到一个错误，即没有安装Nokogiri

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

有什么帮助吗？

请先尝试一下：

$  apt-get install libxml2-dev libxslt1-dev

此外，如果您正在使用rvm，请执行以下操作：

$ rvm requirements

Ubuntu12.10采用了Debian的强化包装，其中包括一组导致此编译错误的GCC默认标志。我们已经在Nokogiri 1.5.4和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

请参阅。

无论是谁投票认为这是离题的，它都不是。这完全是关于堆栈溢出的主题。您是通过RVM安装ruby的吗？还有，为什么不使用1.5.6呢？因为我尝试绑定的gem给出了一个错误，即没有安装nokogiri 1.5.2。。。我还尝试在没有指定版本的情况下安装nokorigi，但没有成功…您可以更改Gemfile以指定较新的版本。然后不确定。我在rubygems.org的Ubuntu12.10中安装了1.5.6。唯一的区别是我使用的是ruby 1.9.3，而你的是ruby 1.9.1。如果可以，请尝试升级。或者试着找出nokogiri的确切版本，也就是抱怨它使用的宝石。这可能也有帮助谢谢，你救了我！
