ExecJS::RuntimeError on Windows trying to follow rubytutorial

Question

UPDATE: Colin\'s suggestion of removing the line //= require_tree . has fixed the issue.

I have wasted over 2 days trying to follow every suggestion

For windows users, this may work. There is a problem with coffee-script-source >1.9.0 running on windows.

It seems you have to add this to your gemfile:

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

then do

bundle update coffee-script-source

I tried all the above options, and also mixed up a few combinations of them, till I found this Rails-4, ExecJS::ProgramError in Pages#welcome and had done multiple system gem updates and bundle installs and updates.

I reverted all my trials and downgraded my coffee-script-source and it works. Posting here to help out anyone else, who may have a similar issue.
