Deploying to Heroku using rails Error

Question

I'm following along Michael Hartl's rails tutorial and am trying to deploy something to Heroku. Everything goes well until i run

    git push heroku master

as I get this error.

I'm guessing that it's due to heroku not being able to run ruby 2.0.0 but I checked their documentation and found that 2.0.0 is still valid on heroku. Here's the link https://devcenter.heroku.com/articles/ruby-support#supported-runtimes .

I'm on Rails 4.0.8 and Ruby 2.0.0

Gemfile

source 'https://rubygems.org'
ruby '2.0.0'
#ruby-gemset=railstutorial_rails_4_0
gem 'rails', '4.0.8'
gem 'bootstrap-sass', '2.3.2.0'
gem 'sprockets', '2.11.0'
group :development, :test do
  gem 'sqlite3', '1.3.8'
  gem 'rspec-rails', '2.13.1'
end
group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
# Uncomment this line on OS X.
# gem 'growl', '1.0.3'
# Uncomment these lines on Linux.
# gem 'libnotify', '0.8.0'
# Uncomment these lines on Windows.
# gem 'rb-notifu', '0.0.4'
# gem 'wdm', '0.1.0'
end
gem 'sass-rails', '4.0.3'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.1'
gem 'jquery-rails', '3.0.4'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'
group :doc do
  gem 'sdoc', '0.3.20', require: false
end
group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

Thanks in advance

Answer 1

由于它是测试站点，因此您可以在Gemfile中注释ruby版本，然后提交并推送到heroku

Answer 2

Heroku doesn't support Ruby 2.0.0. Like it says in the errors, you can find which ruby runtimes work here

Answer 3

在Gemfile中注释ruby'2.0.0 ruby '2.0.0'并推送到heroku。
