-----> Your application is requiring a file that it can't find.

My App is crashing as it can't find gbarcode - which I don't wish to use any more. I have uninstalled the gem from my development environment and wish to push it to heroku. How can I get my app booting without the gem?

You are requiring the gem through the barcoder plugin.

Uninstall barcoder plugin by deleting the vendor/plugins/barcoder directory and all will be fine.

Still unsure of the exact fault.

In the end I created a new heroku app, duplicated the local files and repointed my domain names. The app now works perfectly.

This is a cheap workaround - but it seems to work.
