Edit: Debugging has got me further. Question clarified.
We have installed Ruby, RubyGems and Rails and have forked the shopify_app project. We have created a new rails applications and added three items to the Gemfile: execjs, therubyracer and shopify_app.
Running rails s in order to start our rails application returns this trace:
root@ubuntu:/usr/local/pete-shopify/cart# rails s

I haven't modified any files since forking from Github. Lines 1 - 6 of login_protection.rb are as follows:
module ShopifyApp::LoginProtection
extend ActiveSupport::Concern
included do
rescue from ActiveResource::UnauthorizedAccess, with: :close_session
end
I've looked into this and it seems that the error is caused by a new-style hash syntax between Ruby 1.8 and 1.9; key : value instead of key => value.
Running ruby -v from the command line returns ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]. This would seem to be OK... but I did some debugging, and inside the file /var/lib/gems/1.8/gems/shopify_app-4.1.0/lib/shopify_app.rb (at the top) by putting this:
puts RUBY_VERSION
exit
It printed 1.8.7. **Why are ruby -v and RUBY_VERSION giving me different results? And am I correct in assuming this is the cause of my problems?
Note: To upgrade Ruby I installed the later version with apt-get and then switched to it by using update-alternatives --config ruby and selecting option 2 like this:
root@ubuntu:/usr/local/pete-shopify/cart# update-alternatives --config ruby
There are 2 choices for the alternative ruby (providing /usr/bin/ruby).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/bin/ruby1.8 50 auto mode
1 /usr/bin/ruby1.8 50 manual mode
* 2 /usr/bin/ruby1.9.1 10 manual mode
Also note: We're PHP/Python developers so this is all new to us!
Summary:
1 - Am I right in determining the cause of the syntax error?
2 - Why does RUBY_VERSION and ruby -v give me different results?
