無法推送到Heroku的Rails應用找不到rake-10.4.2

Question

通過Hart的rails教程工作，無法克服此錯誤：

remote:        Your Gemfile has no gem server sources. If you need gems that are not already on
remote:        your machine, add a line like this to your Gemfile:
remote:        source 'https://rubygems.org'
remote:        Could not find rake-10.4.2 in any of the sources
remote:        Bundler Output: Your Gemfile has no gem server sources. If you need gems that are not already on
remote:        your machine, add a line like this to your Gemfile:
remote:        source 'https://rubygems.org'
remote:        Could not find rake-10.4.2 in any of the sources

但是我肯定已經安裝了Rake，並且在我的Gemfile中提供了“ https://rubygems.org ”

這是我的Gemfile：

source 'https://rubygems.org'

gem 'rails',                '4.2.0.rc3'
gem 'sass-rails',           '5.0.0.beta1'
gem 'uglifier',             '2.5.3'
gem 'coffee-rails',         '4.1.0'
gem 'jquery-rails',         '4.0.0.beta2'
gem 'turbolinks',           '2.3.0'
gem 'jbuilder',             '2.2.3'
gem 'sdoc',                 '0.4.0', group: :doc

group :development, :test do
  gem 'sqlite3',     '1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

有任何想法嗎？

嘗試將麒麟寶石添加到生產中。

Answer 2

我有同樣的問題。 原來是因為我使用的是ruby 1.9.3，默認情況下，heroku使用的是2.x。 解決方案是通過添加以下行來在Gemfile中顯式指定您的ruby版本：

紅寶石“ 1.9.3”

提交並推送后，它運行完美。

有關指定您的Ruby版本的詳細信息，請參見https://devcenter.heroku.com/articles/ruby-versions 。
