Rails ExecJS::ProgramError in Pages#home?

ruby-on-rails windows turbolinks execjs

Solution 1

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.

Solution 2

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

Solution 3

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.

Solution 4

in windows coffee-script source >= 1.9.0 not work properly. just add in Gemfile

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

and run

bundle update coffee-script-source

Solution 5

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

gem 'execjs'

into the Gemfile.

Starting a new app, when I create a controller page home and try to go to local host:3000/pages/home, I get the following error:

Showing c:/Users/Doesha/desktop/pinplug/app/views/layouts/application.html.erb where line #6 raised:

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?

Michael Petch over 9 years

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

jameshwart lopez about 9 years

it works on mine also but if we try to look at the console default.js is 404 already

Also, restart the server (somewhat obvious, but It got me).
e-fisher over 8 years

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.
user4571629 over 8 years

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,
TylerH over 8 years

What makes you think this is a better solution than the year-old accepted answer?
Jonathan Harvey about 8 years

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.
illiquent about 8 years

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.
illiquent about 8 years

this solution works on windows 10. make sure you restart the server like Jeff says.
MSC about 8 years

I am on Windows 10 and I agree with e-fisher (above). Changing 'application' to 'default' merely prevented the app from finding the appropriate JS and CSS files. To get the app to find and execute application.js without error, I needed to downgrade coffee-script-source.

Over a year later now Rails 5.0.0.1 and the same bug. Looks like nobody cares about Windows, it is like a tax, if you chose Windows and develop in Ruby on Rails then you waste time. But seriously, this nuance has to be fixed please.

Angelo's solution worked for me (I'm using Rails 4 on Windows 10 x64). Nothing else worked for me, but downgrading to coffee-script-source 1.8.0 did the trick. Thanks, Angelo! P.S. I really wish the Rails devs would fix this, Windows gets no love. :(
