我已经制作了一系列简单的应用程序，并且我已经在我的gemfile中为过去几周内的每个应用程序安装了相同的宝石，出于某种原因，这次我遇到了一些麻烦
当我bundle我的Gemfile，然后尝试启动rails服务器或rails控制台时，我收到以下错误：
Aarons-iMac:ripelist AaronWilliamson$ rails s

我的rails -v是4.1.0 我的ruby -v是ruby 2.1.0p0（2013-12-25修订版44422）[x86_64-darwin13.0]
最后一点，当我运行bundle update时，没有任何变化。
有人能指出我正确的方向吗？我现在几天都在修修补补。谢谢。
答案 0 :(得分：0)
根据您Gemfile.lock，您使用版本为0.9.5的导轨。
修改您的Gemfile并将第3行更改为：
gem 'rails', '4.1.0'
然后运行bundle update
