Currently using the Aptana Studio 3 plugin for eclipse (3.4.2) and I'm unable to start my rails 4.0 project.
Error: Ruby program /xx/xx/xx/xx/HelloRails/script/rails does not exist.
It looks like Aptana is still looking for the rails executable in script, while it moved to bin in rails 4.0. Is there any workaround/fix available for this?
Create a folder script in the root of the app and place rails file from the bin folder to the script folder then it will work.
You might need to change the web-server options in the aptana setting also.
I was having the same problem but this fix fixed it
