I also downgraded the turbolinks gem from 2.3.0 to 2.2.2, thinking that the newer version of the turbolinks gem was causing my app to have errors; obviously that didn't work for me.

Any suggestions on what could be going wrong with my app?

Reset to default
141

In your /app/views/layouts/application.html.erb lines 5 and 6, change the first parameter from application to default.

I met the same problem, too for my situation, I don't know why, but it only happens on Windows. The parameter application works on the web server.

Huh! Same thing for me after I upgraded from Rails 4.1.1 to 4.2 on Windows. Thanks for the answer. Nothing in the upgrade docs about this at all! #@^$@# So how did you figure this out?
coffee-script source >= 1.9.0 don't work properly under Windows. You can do this: gem 'coffee-script-source', '1.8.0' to force 1.8.0 and then issue bundle update coffee-script-source
Thanks @MichaelPetch, your comment is the thing that worked for me!
Changing 'application' to 'default' won't solve the problem, if you check dev tools you'll see assets are not included due to 404. Downgrading coffe-script-source is the correct answer.
I agree with @excel66 - That's right, I can't believe people actually doing that or making this answer as a positive one, that's really not the solution because let's say you have CSS file on this folder \assets\stylesheets it won't load it,

If you are running in WIndows, the coffee-script-source 1.9.0 does not work on windows.

Change it to a previous version adding this line to your Gemfile:

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

And then reinstall the bundle adjusting the dependencies for the new Gem version with:

bundle update coffee-script-source

Also, restart the server (somewhat obvious, but It got me).
this solution works on windows 10. make sure you restart the server like Jeff says.
Hi sir, I did what you've said.. it's still not working.. Why?

I've been having this issue for a while and having gone through all the answers in this thread and found them all to be unsuccessful, I've decided to add my solution in hopes that it helps future Rails users.

I've done everything in this thread - changing application to default allows it to go through without an error, but then once you actually try to use any JavaScript, an error is displayed regarding not being able to find default.js. I've installed NodeJS and put it in my Ruby/bin folder. That did nothing, so I removed it.

You can indeed temporarily get around this problem with the "switching out application with default" solution, but it's extremely short term. This solution may work for you if you have no intention of styling or adding JavaScript to your app through the Rails asset pipeline. I have not tested this myself, but I imagine including JavaScript and stylesheets in the application.html header file may work. But then you lose the magic of Rails.

I have had this issue on Windows 8, Windows 10, and Ubuntu platforms.

The only thing that solves it, for me, and still renders the JavaScript and stylesheets is to first change application to application.css for the stylesheets (even if you're using Sass/SCSS, because it still compiles down into css) and application.js for the JavaScript link. Once that is done, go into your /assets/javascripts/application.js file and delete the // in front of //= require turbolinks.

And now your application should work just fine.

This is probably a deeper issue with turbolinks, but this is a quick workaround that hasn't let me down yet.

this solution worked for me on windows 10, and allowed ruby to see the other style sheets I had in the "pipeline". changing 'application' to 'default' - indeed breaks the stylesheets. perhaps it is just a coffescript error at the cause - but this solution worked great.
wow; I'd give you +150 if I could. thank you so much. this worked on win 7 x64
I had the same issue, and changing "application" to "default" threw the exception that "application.css" couldn't be found. but, this solution did work for me. thanks!

Just install NodeJS on your local machine (make sure the correspodning entry is added to the PATH) and add

gem 'execjs'

into the Gemfile.

I had not realized that NodeJS wasn't installed on my machine. I found this video which basically solves it the same way youtube.com/watch?reload=9&v=l04kFL3pnEk and speaks to installing NodeJS on a windows machine.

On windows 10 version 1511, adding gem 'coffee-script-source', '1.8.0' to my gemfile and then ruby bin\bundle update coffee-script-source from the project directory worked. NB: the previous coffee-script-source version that got replaced was 1.10.0

What makes you think this is a better solution than the year-old accepted answer?
I think this is a better solution because changing "application" to "default" in the /layouts/application.html.erb can cause CSS and JS files throw a 404. Installing Node.js doesn't require you to make changes in your code that either produces undesired results (scripts and stylesheets not loading), or causes you to have to make widespread changes in code when moving to production.
Works on Windows 10 too. Tested

I had this issue too. I went into Sublime into my project folder. Then clicked the app folders, view folder, layout, clicked application.html.erb and changed lines 5 and 6 'application' to 'default'. Worked great. Thanks for posting your problem and thank you to those that answered!

I just wanted to add I went in through Sublime. I am just learning and I didn't understand how to access the .erb file. Just wanted to help others.

Finally got it working what a sigh of relief. Even though I am not exactly sure what made it work. Tried all of the following. 1) Installed node.js , added coffescript npm to it, and restarted. 2) Added gem for exec.js and modified runtime.rb so that it is not able to use default windows script file. Refer to this link on how to do this: [https://github.com/sstephenson/execjs/issues/81][1] 3) To be safe, also added rubyracer gem gem 'therubyracer', platforms: :ruby

In summary added two scripting engines , nodejs and rubyracer and added execjs so that it chooses the best scripting engine , but is not able to choose windows scrpting engine.

I guess just installing nodejs alone might have worked after adding execjs. However I did not restart(post nodejs installation) and tried all the other things.

I tried all of the solutions above, and the only one that worked properly was to install node.js, add the directory to the 'path' environment variable in windows (found in Advanced System Settings, Envirnment Variables, path) and then restart the computer and server. I think the later versions of coffee-script-source must be dependent on node.js, along with other gems. I had the identical error without using coffee-script-source.

Changing 'application' to 'default' is a terrible solution though, because it just removes all of the application's css styling. I do not recommend it at all.

Its problem with turbolinks gem so its creating error

So in app\views\layouts\application.html.erb change this

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

from 

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

and uncomment the line no.15 in app\assets\javascripts\application.js 

require turbolinks

and copy it into app\assets\stylesheets\application.css at the end of file

From this your css and js will be run

I am on Rails 5.1.6. I had the same issue. As recommended above I degraded the coffee-script-source gem which solved the issue.

# Use CoffeeScript for .coffee assets and views gem 'coffee-rails', '~> 4.2' # <-- This existed already gem 'coffee-script-source', '1.8.0' # <-- Adding this line solved the problem

Note: I didn't modify application.html.rb file

we should only change line 6 from application to default in /app/views/layouts/application.html.erb . changing line 5 will result in stylesheets not loading.

You need to read the instruction in the rails page. You need ExecJS gem and some JS runtime.

More practical: 1.- Install some Runtime JS, for example node.js

2.- get ExecJS gem-> gem install execjs

Explication:

From the rails page:

"Compiling CoffeeScript and JavaScript asset compression requires you have a JavaScript runtime available on your system, in the absence of a runtime you will see an execjs error during asset compilation. Usually Mac OS X and Windows come with a JavaScript runtime installed. Rails adds the therubyracer gem to the generated Gemfile in a commented line for new apps and you can uncomment if you need it. therubyrhino is the recommended runtime for JRuby users and is added by default to the Gemfile in apps generated under JRuby. You can investigate all the supported runtimes at ExecJS."

From hte gitHub of ExecJS:

"ExecJS lets you run JavaScript code from Ruby. It automatically picks the best runtime available to evaluate your JavaScript program, then returns the result to you as a Ruby object.

ExecJS supports these runtimes:

therubyracer - Google V8 embedded within Ruby therubyrhino - Mozilla Rhino embedded within JRuby Duktape.rb - Duktape JavaScript interpreter Node.js Apple JavaScriptCore - Included with Mac OS X Microsoft Windows Script Host (JScript) Google V8 mini_racer - Google V8 embedded within Ruby"
