我正在使用rvm 1.23.16 (stable)构建我的Ruby环境，并且可以看到Ruby将ruby 2.0.0-p247传递给ruby-2.0.0-p353，现在如果尝试安装Rails 4.0 rails gem install rails -v 4.0.0或{{ 1}}（为了省略安装过程的文档，就像我最近学到的那样）我有以下错误：
gem install rails -v 4.0.0 --no-rdoc --no-ri. Building native extensions. This could take a while...
ERROR: Error installing rails:
ERROR: Failed to build gem native extension.
