Hey Martin,

I'm not sure what's going on here, but I'll notify Jim and Jason so they can take a look and get back to you. :)

Did you run bundle install? If so check your Gemfile and make sure the line "gem therubyracer" is not commented. Meaning make sure the line doesn't start with #. Save and run bundle install.

That should do it. It can't find a JavaScript runtime on your computer and therubyracer will get you set up

On windows you do not need "The Ruby Racer", it should remain commented out Jim. Ruby racer does not have a windows binary and will not work. Windows has its own JS runtime.

I've seen this a couple of times. Here's a possible fix:

Download and install nodejs from http://nodejs.org/download/.

Add the following to the Gemfile:

gem "execjs"

Then run "bundle install" and try it again.

yes, this worked for me! Thanks Jason, didn't even need to add to the Gemfile, just ran command prompt through node.js . Thanks!

THanks for all the tips, I'm afraid I'm a newbie so I'm not sure if I did that correctly:

1 - Installed node.js

2 - went to treebook folder and edited 'gemfile' in sublime to add: gem "execjs" to line 40 (at the end)

3 - saved the folder

4 - opened 'command prompt with ruby and rails' cd to treebook\ directory

5 - 'bundle install'

6 - 'rails server'

after this I still had the same issue... I get the welcome page @ http://127.0.0.1:3000/

but still receive those errors @ http://127.0.0.1:3000/statuses/

I'll tr

I'll try restarting and see how it goes, please let me know if you can see where I'm going wrong! Here is the text from my gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.1'

Bundle edge Rails instead:

gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'

Gems used only for assets and not required

in production environments by default.

group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes # gem 'therubyracer'

gem 'uglifier', '>= 1.0.3' end

gem 'jquery-rails'

To use ActiveModel has_secure_password

gem 'bcrypt-ruby', '~> 3.0.0'

To use Jbuilder templates for JSON

gem 'jbuilder'

Use unicorn as the web server

gem 'unicorn'

Deploy with Capistrano

gem 'capistrano'

To use debugger

gem 'ruby-debug19', :require => 'ruby-debug'

gem "execjs"

Heres what I did to fix mine:

Installed the nodejs exe file ( I skipped the gems part ) then ran the rails installation again. (railsinstaller.exe)

@Kerde, thanks, re-installing rails after installing node.js seems to have done the trick!

I installed node.js and re-installed rails, and I'm still getting this problem.
