我对Ruby on Rails很新，我决定使用LocomotiveCMS来满足我的应用需求。
我在理解这些概念时遇到了一些麻烦，而且我遇到了宝石依赖的问题！
我只是试图创建一个Rails控制器，因为我试图掌握使用机车/旅行车，但遇到了以下情况：
chloe@chloe-VirtualBox:~/fyp/locomotiveapp$ rails generate controller Book

我正在使用带有Xubuntu的VirtualBox实例，我使用的是Rails 5.0.0.1，Ruby 5.0.0.1和LocomotiveCMS 3.1.1
我有一些依赖关系的问题，因为locomotivecms 3.1.1需要使用Rails 4.2.6，但我在Gemfile.lock文件中改变了这个（我看过的另一个页面），但现在我真的很难过;任何帮助/建议将不胜感激！
这是我的Gemfile.lock：
