Heroku rejecting push in mature application (pre-receive hook declined)

Question

I\'m getting

   FAILED: http://devcenter.heroku.com/articles/bundler

! Heroku push rejected, failed to install gems via Bundler To git@hero

Answer 1

You have modified your Gemfile in development but did not check
the resulting snapshot (Gemfile.lock) into version control

This means that you have added gems to you gemfile but have not updated to. The Gemfile.lock is out of sync with this file.

You need to update your bundle.

Run this command in console in your app's directory: bundle

Then do git push heroku

And you should be good to go.

**Nuke the app and start over.

gem install taps #install taps
heroku db:pull   #pull your data to your local machine

rm -rf .git #remove your git repo 
git init    #create a new repo
git add .   #add all the files
git commit -m 'master' #commit as master

heroku create #create a new heroku app
heroku rename myapp #rename the app
git push heroku master #push to heroku

heroku db:push #push your data to heroku

And that should get a new app up.
