javascript_include_tag throws unsupported method

Question

I recently created a new project with Rails 4.2.0 and created a controller called Land for the landing page. So, I ran into this error upon visting http://localhost:3000/land/home:

Started GET "/" for ::1 at 2015-02-27 15:56:23 -0600

Is there a way of getting rid of this error? Or is it a bug?

I've had this sort of error when my js is broken. I guess the question is what js have you added? I highly doubt it's a bug. — jcuenod, Feb 27 '15 at 22:31
If you think there's a problem with turbolinks, you can turn it off in your Gemfile (just remove it) and you can `bundle update` (I'm using it though and I can tell you I'm pretty confident it's working) — jcuenod, Feb 27 '15 at 22:39
All I have is the application.js and the land.js.coffee at this point. I'm also doubting that is a bug. I dunno. — Rod Argumedo, Feb 27 '15 at 22:42
What's in them though? Try removing `land.js` and see whether you get that error (I'm assuming you haven't done much to `application.js` — jcuenod, Feb 27 '15 at 22:45
I must admit, I probably can't help you with this without seeing your code - is it on github or anything? I am fairly confident this is not a bug with rails though. — jcuenod, Feb 28 '15 at 12:58
@jcuenod I just pushed it to GitHub now. Feel free to mess with it. https://github.com/rodrigoargumedo/ENV-test — Rod Argumedo, Mar 02 '15 at 14:06
Have you tried removing `'data-turbolinks-track' => true`? (and the comma just before it) — jcuenod, Mar 02 '15 at 15:22

I recently found another solution for this problem. gem 'coffee-script-source' in 1.9.0 has some issues with Rails on Windows. I reverted to the previous version using gem 'coffee-script-source', '1.8.0' in the Gemfile, this will resolve your problem.

Another way of solving this exception is installing Node.js onto your machine and the error should go away after installing & restarting rails server. Make sure that you add Node.js into your PATH before restarting the terminal(s) and rerun the server.

It works both ways. Although, I can put back turbolinks when `coffee-script-source` is down to 1.8.0. – Rod Argumedo Jun 11 '15 at 13:26

I had the same problem and this solution worked nicely. I'm also on a Windows machine. – Franco Jun 15 '15 at 23:24

This one solved mine too on Windows 10 computer, thanks a lot – Ashutosh Sep 19 '15 at 16:17

changing coffee version encountered another problem, but installing node.js solved the problem. Note, you need to add node to PATH after you install it and then start a new command line and restart the rails server – BillOverFlow Sep 02 '16 at 18:29

Ahh, it seems that you are missing

//= require turbolinks

in your application.js

See this on removing turbolinks (and obviously make sure it's all in place if you want it running).

@jcuenod in my application.js the code you specified is availble and did not solve my problem – jameshwart lopez Jun 24 '15 at 10:30

I am running Windows 10, Ruby 2.1.7p400 and Rails 4.2.4. I could not get gem coffee-script-source '1.8.0' to install as gem insisted on version 1.9.1.1. I tried changing ExecJS to use UTF-8 encoding and running cscript without the //U switch as in this post without any luck as well.

I ended up placing nodejs.exe in the Ruby\bin folder and the issue was resolved.
