I've bben trying to deploy a Ruby application to Heroku. The application works fine locally but I keep getting this error when I try and deploy.

Being very new to Ruby I'm not sure where I'm going wrong.

I've removed the the bootstrap-theme.css.map to see if that would make a difference.

I've been trying all week to get this working and keep getting to this point and get no further. 

ruby 2.2.0p0 (2014-12-25 revision 49005) [x86\_64-darwin14]
Rails 4.2.0

Any ideas

Thanks
