Question

I am working with an app and wanted to deploy it on heroku but I was getting some error messages and a build failed on heroku.

Below is my gemfile

Answer 1

Does not that mean simply that your Gemfile/Gemfile.lock in heroku are out of sync? If bundle install modifies Gemfile.lock, you should commit that and then push to heroku.

Another problem could be too old bundler. gem update bundler ; bundle install would fix that problem, if that's an issue.
