似乎是我生成了一个新的控制器，然后生成了integration_test user_pages，然后整个事情变得混乱。我无法为我的生活弄清楚我做错了什么或从哪里开始。我甚至试图摧毁两者，同样的错误出来了。请帮忙！

答案 0 :(得分：0)
请检查您的控制器。内容应该是这个
#app/controllers/users_controller.rb
class UsersController < ApplicationController
def new
end
end
和您的routes.rb
#config/routes.rb
FirstApp::Application.routes.draw do
get "users/new"
root to: 'pages#home'
在rails s之前运行以下命令，以防万一：
bundle install
bundle update
rake db:migrate
有时rake db：reset可能有所帮助，但这会破坏并重建您的开发环境中的数据库。
