Rails服务器将无法运行-未初始化的常量使用（NameError）

[英]Rails server won't run - uninitialized constant use (NameError)

问题描述

I ran a bundle install and since have not been able to run rails s successfully within terminal. 我进行了捆绑安装，由于无法在终端中成功运行rails。 I am new to rails and have tried to find help on this but nobody can explain it to me in the 101 way. 我是Rails的新手，并试图在此方面寻求帮助，但是没人能以101的方式向我解释。 What is going wrong - it looks like this is a NameError? 出了什么问题-看起来这是NameError吗？

I think that you have typed Use instead of use, perhaps in config/routes.rb 我认为您可能在config / routes.rb中键入了Use而不是use。

Case is important, if it starts with a capital letter then it is a constant, rather than a function. 大小写很重要，如果它以大写字母开头，则它是一个常量，而不是一个函数。
