"Cannot load such file" error when deploying Rails app to Heroku

I'm using a gem for gmail in my Rails app. My Gemfile contains:

gem 'gmail-api-ruby', :require => 'Gmail'

And in my controller, I initialize the gem with (using devise/omniauth to get the refresh_token from Google):

Gmail.client_id = ENV['CLIENT_ID']
Gmail.client_secret = ENV['CLIENT_SECRET']
Gmail.refresh_token = current_user.refresh_token

This works fine in development, but when I deploy to Heroku, I get the following error:

/app/vendor/bundle/ruby/2.2.0/gems/bundler-1.7.12/lib/bundler/runtime.rb:76:in `require': cannot load such file -- Gmail (LoadError)

I cannot figure out why. Should I be requiring the gem somewhere else in my app?

require is case sensitive if the underlying filesystem is case sensitive (which it is on linux, which is what underpins heroku)

Change to :require => 'gmail' instead of Gmail and you should be ok.

Just remove useless require option from your Gemfile because bundler can load classes inside of this gem without specify require option in your case.

gem 'gmail-api-ruby', '~> 0.0.10'

and run bundle install.

FYI: read section about require option here.
