#3 楼 @ken 不会吧？只是‘/notifications’这个页面才会出现这个情况哦

不明白为什么，routes 文件里面是已经有root to: 'welcome#index' 了

新的通知功能上线 - 基于 notifications 这个 Rails Engine gem at 2016年04月16日

不过不知道为什么在我的 shell 里运行这句代码时：

rails g notifications:install

会出现这个：

Adding Homeland initializer (config/initializers/notifications.rb)...
      create  config/initializers/notifications.rb
Adding model (notification.rb)...
      create  app/models/notification.rb
Error: Command 'notifications:install:migrations' not recognized
Did you mean: `$ rake notifications:install:migrations` ?

Usage: rails COMMAND [ARGS]

The most common rails commands are:
 generate    Generate new code (short-cut alias: "g")
 console     Start the Rails console (short-cut alias: "c")
 server      Start the Rails server (short-cut alias: "s")
 dbconsole   Start a console for the database specified in config/database.yml
             (short-cut alias: "db")
 new         Create a new Rails application. "rails new my_app" creates a
             new application called MyApp in "./my_app"

In addition to those, there are:
 destroy      Undo code generated with "generate" (short-cut alias: "d")
 plugin new   Generates skeleton for developing a Rails plugin
 runner       Run a piece of code in the application environment (short-cut alias: "r")

All commands can be run with -h (or --help) for more information.
