Answer 1

You can’t run sqlite on Heroku- try using the postgres gem pg instead. Make sure the reference to the sqlite gem is either commented out or in a development only group (group :development do . . .end) in the gemfile. Then add the gem for postgres (gem pg). Then do bundle install --without development and try the push again
