试图在xubuntu上安装rails 14.04错误：无法构建gem原生扩展

gem install rails不适用于我。我从这个网站http://installfest.railsbridge.org/installfest/linux（当然是最新版本）一步一步地做了一切，然后我unistalled红宝石，红宝石宝石，rvm，并从本网站https://gorails.com/setup/ubuntu/14.04做的一切都没有工作。我见过许多相关的主题，并尝试了很多解决方案，但似乎没有任何工作适合我。我尝试了ruby-dev，ruby-all-dev，重新安装ruby，我确定我已经安装了rvm的要求。我找不到任何能解决问题的东西，所以希望你们能帮助我。试图在xubuntu上安装rails 14.04错误：无法构建gem原生扩展

如果您使用的是红宝石版本管理，尝试切换到红宝石2.2.2。并尝试再次安装宝石。我有同样的问题，我通过切换到Ruby 2.2.2成功安装了我的宝石。也许它是一个红宝石2.2.3的问题。

'成功安装了rails-4.2.4'非常感谢。只是为了澄清，如果我使用ruby 2.2.2安装rails，那么我不能在ruby 2.2.3上使用rails吗？ – dddeee

这取决于您使用的是哪个版本管理器。 RVM将宝石放置在“rubyversion/gemset/gems”文件夹中，因此每个宝石都特定于ruby版本和ruby版本中的gemset。尝试文档并查看安装宝石时是否有“全局”选项。 –
