Heroku, bundler fails on missing dependencies

Question

I have had trouble recently trying to deploy my rails app on Heroku. In the past, I had deployed apps on Heroku with no problem, but Heroku does not support ruby 2.0.0 anymore. They suggest adding ruby "2.2.4" to the Gemfile, which is what I did. The beginning of my Gemfile is as follows:

source 'https://rubygems.org'
ruby "2.2.4"

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.0'
# Use pg as the database for Active Record
gem 'pg'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
...

So, I have run bundle install with version 1.7.8 on my computer with no problem. I can even run my app in production mode. However, when I try to deploy the app on Heroku, I get this:

Any help is greatly appreciated.

Are you saying that I should run ` heroku config:set BUNDLE_WITHOUT="development:test" ` on the command line? — LearnMoreCoding.com, May 01 '16 at 03:32

I'd suggest deleting your Gemfile.lock, running bundle install again locally, committing the new Gemfile.lock to your git repository and then try your git push heroku master again.

@orangeplus same deal. you should try to delete your gemfile.lock. The error message says that it is corrupt, which I would imagine is because when it was originally generated you were using ruby 2.0.x and now you have specified a more recent version. So you need to regenerate your Gemfile.lock with that specification at the top. Not certain, but it seems feasible. – Jeremy Gunter May 01 '16 at 03:49
@orangeplus You're very welcome, I'm glad I was able to help. Pushing to Heroku can be a bitch sometimes. :) – Jeremy Gunter May 07 '16 at 03:48

I had the same problem and what I did was I updated Ruby 2.2.4 in my system and restarted terminal, then followed these steps:

bundle install
bundle update 
git push heroku

( it’s a good idea to update the gems with bundle update to make sure the versions match)

The problem is that you only changed the Ruby version number in the Gemfile, but did not recreate a valid Gemfile.lock. This leads to a Gemfile.lock that contains Gems in versions that are not compatible with Ruby 2.2.4.

If you change something in the Gemfile then you have to update or recreate the Gemfile.lock with the same Ruby version before pushing to Heroku.

I suggest to use a Ruby version manager (like rbenv or RVM) to be able to run multiple versions of Ruby on your development machine. Then update the Ruby version in your application by changing the Ruby version in Gemfile (for Heroku) and .ruby-version (for your local environment). Both version must match.

Once that is done, run bundle install to update the Gemfile.lock or (when there were major updates or you just want to ensure that you use the latest versions) run bundle update to recreate the Gemfile.lock.
