BUG Segmentation fault ruby 2.0.0p481（2014-05-08修订版45883）x86_64-darwin13.2.0
尝试运行rails s或rails c时收到错误。
我最近通过自制软件和rbenv安装了ruby和rails。 当我运行rails new project ，应用程序已成功创建。 然后我在相应的目录中进行bundle install ，当我运行rails s或rails c时，一切都顺利更新。 出现以下错误：

正如所承诺的，这是答案：
你以前用过rvm了吗？ 因为我从堆栈跟踪中看到的是rbenv和rvm都被调用。
如果是这种情况，请完全删除rvm并从头开始重新安装rbenv。
