未安装Nokogiri依赖项libxml和libxslt

Question

我在Ubuntu 12.10 64位上使用Ruby 2.1。我无法安装Nokogiri，因为它需要libXSLT和libxml。我试图安装这两个，但得到了这个错误：

***@***:~$ sudo apt-get install libxslt-dev libxml2-dev

我也尝试添加了12.04的安全更新，但仍然没有成功。

我运行了sudo apt-get update，但问题仍然存在。

当我运行bundle install或gem install nokogiri时，我得到以下错误：

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

试试这个：

sudo apt-get install libxslt-dev libxml2-dev zlib1g-dev
sudo gem install nokogiri

您需要在计算机上安装所有必需的库。当您安装RVM时，它应该已经为您列出了以下内容。在当前版本的rvm上，您可以运行rvm requirements查看确切的列表。我希望这能帮助你..
