Rails 3.2.3 ExecJS::RuntimeError

I'm getting ExecJS::RuntimeError when i try to start Rails server and the server log gives me the following:

   ActionView::Template::Error (delete operand may not be argument or var
      (in /home/sergey/Perfecto/arena/app/assets/javascripts/items.js.coffee)):
        47:         <%= raw flash_messages %>
        48:     </div>
        49: 
        50:     <%= javascript_include_tag "application" %>
        51:     <%= yield :javascripts %>
        52:     <%= yield :scripts %>
        53: </body>

I found that this error happens because Ubuntu don't have a javascript runtime installed. Okay. I've installed nodejs v0.6.3 from sources and tried to add gem 'therubyracer' to my Gemfile as it was suggested but the error still apperars.

What have i missed? Thanks in advance.

My items.js.coffee looks like this:

                return false

        $(".draggable_item, #new_items_queue").disableSelection()

Older thread but I had the same issue as well but solved it by simply renaming my javascript and deleting the '.coffee' at the end of all the file names.

For example:

From:

'name'.js.coffee

to:

'name'.js

For some reason or another this worked.

You have this in your CoffeeScript:

google.maps.event.addListener ib, 'closeclick', -> 
    marker.setMap(null)
    delete marker
    $(".draggable_item").draggable("enable")

And the error say this:

delete operand may not be argument or var

If you backtrack through your CoffeeScript from that delete marker, you'll see that marker is an argument and you can't use the JavaScript delete operator on an argument.

You should be able to get rid of that delete marker without causing problems, just the marker.setMap(null) should be enough to make it go away.

Try to add gem "execjs", "~> 1.3.0" at your Gemfile. I guess it can fix this...
