"" Application.js "is not present in the asset pipeline" error in Ruby on Rails

While watching the video of Ruby on Rails application production on YouTube, I will summarize it as a record because the title error occurred while learning in the local environment.

When implementing the logout function ActionView::Template::Error: The asset "application.js" is not present in the asset pipeline And a javascript file does not exist error occurred.

Upon examination, the cause was a different version of rails. On the video, the development environment is rails:, and the Javascript folder is app/assets/javascripts/application.js

But in rails 6 app/javascripts/application.js The place was different.

In the view file head in ails 5.x <%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %> Since it is, I changed it as follows so that application.js can be loaded normally and solved it.


<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>

Since it was the first application production in the local environment, I didn't understand anything and executed rails new [project name] according to the video, and started with the latest version.
