尝试运行rails server

Question

我使用的是ruby 2.3.0和rails 4.2.0。当我尝试运行rails服务器时，我收到的错误似乎与sass-rails gem有关。我不知道为什么这不起作用。

谢谢

这是错误：

roman @ quotebeam：〜/ workspace / hello_app $ rails server /home/roman/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/bundler-1.11.2/lib/bundler/runtime.rb:80:in rescue in block (2 levels) in require': There was an error while trying to load the gem 'sass-rails'.

中的2个级别

这是我的宝石文件
