rails EXECJS runtime error

Question

Hello I am getting a ExecJS::RuntimeError in Demo#index

Below is the line 6 that was highlighted and below that is my full trace. Can someone either A: point me in the right direction to debug this as well as a good reference for debugging rails. I am new to rails. My guess is i'm missing a gem (i checked to make sure turbolinks was there) or something in turbolinks is wrong. I'm using Rails 4 using rails installer (after updating gems and rails and bundle install etc.).

Below is also my gemfile

Line 6 is highlighted:

<%= javascript_include_tag "application", "data-turbolinks-track" => true %>

Below is my full trace:

What is my Gemfile (sorry really enw) or do you mean just a list of gems? As well, I am on windows 8. — kmalik, Jun 11 '13 at 18:57
Also take a look at the link I gave in my initial comment it should help you — Deej, Jun 11 '13 at 19:21
I am facing the same problem and I am also new. I must say that Ruby On Rails requires lots of patiance in learning. — Talha, Oct 09 '13 at 05:46
@kmalik did you ever find a solution to this? Can you update the question with your solution? — Matt, Dec 05 '13 at 15:43

I got the same error and fix it :)

Open the Gemfile
Add these lines: gem 'execjs' gem 'therubyracer'
Save the changes in the file
Execute bundle install on the terminal

I had this issue before and solved it by installing node.js (using the MSI installer).

Hope this helps.

I had the same error using Rails 5.2 and ruby 2.5. In my case the problem was with the gem Bootstrap 4. I was using gem 'bootstrap', '~> 4.1', '>= 4.1.3' I disabled this gem and the Rails started working. For solver the problem, I change the gem 'bootstrap' to gem 'bootstrap-sass', '~> 3.3', '>= 3.3.7'

Don't know if the problem in the question is exactly the same as mine (got the same trace though). Anyway, here is one solution for execjs runtime error on Windows:

This worked for me. This problem occurs mainly in Windows OS. Force your Coffee Script Source version to 1.8.0. Higher versions are not supported properly.

Change or add this to your gem file:

gem 'coffee-script-source', '1.8.0'

then update the coffee-script-source bundle

bundle update coffee-script-source

This should fix the issue.
