TypeError: Object doesn't support this propert

Question

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):

17     <%= csrf_meta_tags %>
18     
19   </head>

This is what I got on the Rails server:

Thank you for any help.

Answer 1

The reason is because NodeJS is not installed. If you install it, the problem should go away.

However, this would work as well in application.js:

//= require jquery 
//= require jquery_ujs 
//= require turbolinks 
// require_tree .

But this is just not the prefered method because all this does is disable rails functionality. For example, ActionCable will not work with this change.

Answer 2

I think Best Solution is Removing the slashes in application.js file like

= require jquery
= require jquery_ujs
= require turbolinks
= require_tree .

Answer 3

I removed the require_tree from application.js and it worked

//= require jquery 
//= require jquery_ujs 
//= require turbolinks 
// require_tree .

Answer 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.

Answer 5

For me,solution was to remove-

 <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload'%>
 <%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>

from

app\views\layout\application.html.erb

Answer 6

If you do not use layouts, put "layout false" in the controller file, just below class title:

class ABCController < ApplicationController "layout false" def index ... ..
