The Rails router recognizes URLs and dispatches them to a controller's action.The error is caused by missing out the mapped action.
Rails 路由器识别 URL 并将它们分派给控制器的操作。该错误是由于缺少映射的操作引起的。
Rails.application.routes.draw do
# url action
get 'script/index' => 'script#index'
get 'landing/index' => 'landing#index'
root 'script#index'
end

You can do it many ways, these all work:
您可以通过多种方式做到这一点，这些都有效：
- get 'script/index'
- get 'script/index' => 'script#index'
- get 'script/index', to: 'script#index'
- 获取“脚本/索引”
- 获取 'script/index' => 'script#index'
- 获取'脚本/索引'，到：'脚本#索引'
Think of pathfirst and controller#methodto follow.
首先考虑路径和要遵循的控制器#方法。
Root is a special case, always: root 'script#index'
root 是一个特例，总是：root 'script#index'

Change
root 'landing/index'to
root 'landing#index'
更改
root 'landing/index'为
root 'landing#index'

I had the same error running rails g.
我有同样的错误运行rails g。
If you run a command that uses routes.rb, the file needs to be error free for the command to work.
如果您运行使用 的命令routes.rb，则该文件需要无错误才能使命令正常工作。
In your case, you had paths, but you didn't match them to actions, so the routes.rbfile was broken. You needed something like get 'landing/index' => 'my_controller#my_action'
在您的情况下，您有路径，但您没有将它们与操作匹配，因此routes.rb文件已损坏。你需要类似的东西get 'landing/index' => 'my_controller#my_action'

Kaleidoscope's code works just fine. Below is a slightly concise version.
Kaleidoscope的代码工作得很好。下面是一个稍微简洁的版本。
Rails.application.routes.draw do
get 'script/index'
get 'landing/index'
root 'script#index'
end
Rails add the left side of the arrow(=>) by convention replacing /with #.
Rails 按照惯例添加了箭头（=>）的左侧，替换/为#。
