在 Rails 5 上运行 rake 路由给出实例化错误

Question

我正在尝试设置一个准系统 Rails 应用程序。到目前为止，我已经生成了一个示例文章模型，向数据库中添加了一些记录，将我的路由配置编辑为以下内容：

Rails::Application.routes.draw do
  resources :articles
end

但是当我运行 bin/rake routes、bundle exec rake routes 和 rake routes 时，我收到以下错误：

$ bin/rake routes                                                                                                                               (articles-controller✱)
rake aborted!
Rails::Application is abstract, you cannot instantiate it directly.

有什么想法吗？我所有的宝石都使用bundle update

糟糕，看起来 routes.rb 文件的语法在 Rails 5 中有点不同。对于遇到此问题的其他人，do 块的语法是 Rails.application.routes.draw do，而不是 Rails::Application.routes.draw do
