Created a Rails 5 app using devise for auth and attempting to add Thredded gem for forums.

Expected behavior

The app should load at http://localhost:3000.

Actual behavior

After server starts, the following message shows up in the chrome browser where the app should be.

couldn't find file 'rails-ujs' with type 'application/javascript'

System configuration

    Ruby 2.4.0p0 (2016-12-24 revision 57164)
    Rails 5.0.4

GemFile
    gem 'pg', '~> 0.18'

    gem 'coffee-rails', '~> 4.2'

  • I think rais-ujs is included with Rails 5.1. Since you're still on 5.0 then Rails is still dependent on jquery for UJS. Then you can just simply remove //= require rails-ujs from your app/assets/javascripts/application.js Commented Nov 6, 2017 at 13:34

Reset to default

gem 'rails-ujs', '~> 5.1.0.beta1'

Include this gem in your gem file or use rails 5.1.4 that has it by default. Or remove it from

app/assets/javascripts/application.js
require rails-ujs #this line remove
