Error when running ruby project



I am receiving an error when trying to run my first cloud9 project.
Freshly downloaded from github.

Thanks for the help.

Hard to say what’s the issue here.

What kind of project is this? Rails?

Would be helpful if you can provide the Rails version and Ruby version in your workspace. Also your Gemfile.


@BigChief45 thanks for the response!
Yes, its a ruby project - currently running 2.3.0
(this works on my local on my mac, trying to migrate it over to


source '
ruby ‘2.3.0’

Bundle edge Rails instead: gem ‘rails’, github: ‘rails/rails’

gem ‘rails’, '~> 5.0.0’
gem ‘puma’, '~> 3.0’
gem ‘sass-rails’, '~> 5.0’
gem ‘uglifier’, '>= 1.3.0’
gem ‘coffee-rails’, '~> 4.2’
gem 'jquery-rails’
gem ‘turbolinks’, '~> 5’
gem ‘jbuilder’, '~> 2.5’
gem 'bootstrap-sass’
gem ‘devise’, '~>4.2.0’
gem ‘roo’, '~> 2.4.0’
gem 'resque’
gem ‘resque-web’, require: 'resque_web’
gem 'therubyracer’
gem 'less-rails’
gem 'twitter-bootstrap-rails’
gem 'slim’
gem ‘sinatra’, github: 'sinatra’
gem 'sidekiq’
gem 'rack’
gem 'railties’
gem 'activesupport’
gem ‘command-runner’

group :development, :test do
gem 'sqlite3’
gem 'listen’

group :production do
gem 'pg’
gem 'rails_12factor’

Windows does not include zoneinfo files, so bundle the tzinfo-data gem

gem ‘tzinfo-data’, platforms: [:mingw, :mswin, :x64_mingw, :jruby]


solved, it was the runner… had the wrong runner selected.
