TypeError: Object doesn't support this property or method
Solution 1
The error occurs because there is some problem finding the correct assets which are located in app/assets. To resolve the issue, you can following below steps.
Add gem 'coffee-script-source', '1.8.0' into Gemfile and run bundle install then Run bundle update coffee-script-source Restart rails server Or there is a dirty workaround which is to change the code from
<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
to
<%= stylesheet_link_tag "default", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "default", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
But note this workaround doesn't really resolve the application issue, it just makes your application works without expected stylesheets and javascripts.
Solution 2
I removed the require_tree from application.js and it worked
//= require jquery
//= require jquery_ujs
//= require turbolinks
// require_tree .
Solution 3
I think Best Solution is Removing the slashes in application.js file like
= require jquery
= require jquery_ujs
= require turbolinks
= require_tree .
Solution 4
I had this issue too, checkout the extensive solution on this thread, ExecJS::RuntimeError on Windows trying to follow rubytutorial by @Kevin P. Also,the solution by, @evedoevelli, on another thread: Rails ExecJS::ProgramError in Pages#home? works. I used the second solution with it been the most recent date-wise.
Solution 5
Upon careful research this is the solution I stumbled upon. Just make sure you have the latest version of NodeJs installed. After installing NodeJs, make sure you restart our system. However it is very important that you update your windows OS. You should be fine. If you are using RubyMine everything should work by now. No need to be troubling your head over the coffee-script issue. The ExecJs Program error seem to be more related to the NodeJs and its associated modules.

I have created rails application where I created a database (empty). When I try to view my products page, I receive the following error on my http://localhost:3000/products page. Before migrating the database, the application did function. I am using therubyracer and am on Windows 7.
ExecJS::ProgramError in Products#index Showing C:/RailsInstaller/DevKit/home/JP/nameofapp/app/views/layouts/application.html.erb where line #16 raised: TypeError: Object doesn't support this property or method (in C:/RailsInstaller/Ruby2.1.0/lib/ruby/gems/2.1.0/gems/turbolinks-2.5.3/lib/assets/javascripts/turbolinks.js.coffee) Extracted source (around line #16): 13 <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script> 14 15 <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %> 16 <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %> 17 <%= csrf_meta_tags %> 18 19 </head> Rails.root: C:/RailsInstaller/DevKit/home/JP/nameofapp
This is what I got on the Rails server:

Thank you for any help.

mgabz over 6 yearsI just added 'gem coffee-rails' and then bundled and everything is back to normal. Just in case this helps anyone, I'm working on windows and built the project using the 'without coffeescript' command.

Joe about 6 yearsThis does not solve the problem and brings up issues with any gem/dependency relying on the js portion of the asset pipeline.

Sprachprofi almost 6 yearsgem 'coffee-script-source', '1.8.0' was the solution. Even coffee-script-source 1.12 still doesn't work on Windows.

Richard over 3 years3 years later and this is still a problem. And this is still the solution. Many thanks!
