ruby-on-rails - 终端重启后路由丢失。 rails 5.0.1

Question

这几天我一直在寻找答案，但一无所获。我知道有很多类似的问题，但他们帮不了我。

我已经开始使用 http://guides.rubyonrails.org/getting_started.html 学习 Rails并一直向前直到终端重启。这是错误消息和代码示例:

walker@DESKTOP-L15NDIS:~/blog$ rails routes
/home/walker/.rvm/gems/ruby-2.3.1/gems/railties-5.0.1/lib/rails/app_loader.rb:40:
warning: Insecure world writable dir
/home/walker/.rvm/gems/ruby-2.3.1@global/bin in PATH, mode 040777
config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

   * development - set it to false
   * test - set it to false (unless you use a tool that preloads your test environment)
   * production - set it to true

 You don't have any routes defined!

 Please add some routes in config/routes.rb.

 For more information about routes, see the Rails guide: http://guides.rubyonrails.org/routing.html.

routes.rb:

Rails.application.routes.draw do
    root 'welcome#index'
    resources :articles
end

config/environments/development.rb:

 config.eager_load = false

config/environments/test.rb:

config.eager_load = false 

config/environments/production.rb

config.eager_load = true

您有什么建议来解决这个问题？

注意:所有这些东西在终端重启之前都运行良好。

附言我创建了另一个应用程序，它在终端重启之前运行良好。

附言我在 Windows 10 专业版上运行 Linux 子系统。

P.P.P.S.我不能使用任何 Linux 发行版或购买 MacBook

对我来说，系统似乎对您的主文件夹的访问权限有问题。

尝试运行 sudo chmod go-w/home/walker 如果其他路径出现问题，请执行相同的操作。

检查相似 question .如果您想在没有“基础设施”问题的情况下尝试 Rails，请查看 https://www.railstutorial.org/以及他们对 cloud9 环境的选择。
