Question

我将rails从3更新到4并将ruby更新到版本2.我在运行更新后尝试运行rails。错误是什么？

/home/aravind/Documents/dev/ptl/config/application.rb:7:in `require': cannot load such file -- active_resource/railtie (LoadError)
from /home/aravind/Documents/dev/ptl/config/application.rb:7:in `<top (required)>'
from /usr/local/lib/ruby/gems/2.0.0/gems/railties-4.0.0/lib/rails/commands.rb:76:in `require'
from /usr/local/lib/ruby/gems/2I .0.0/gems/railties-4.0.0/lib/rails/commands.rb:76:in `block in <top (required)>'

试试这个：

在aplication.rb中评论此行：

require "active_resource/railtie"

如果你有，如果没有，我会删除我的答案，但这解决了我几天前的问题。
