Question

通过Hart的rails教程，无法解决这个错误：

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

但我确实安装了Rake，并在我的Gemfile中提供了“https://rubygems.org”

这是我的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

有什么想法吗？

我完成了迈克尔哈特教程，我的宝石般看起来像这样：

source 'https://rubygems.org'

gem 'rails',                   '4.2.0.beta4'
gem 'bcrypt',                  '3.1.7'
gem 'faker',                   '1.4.2'
gem 'carrierwave',             '0.10.0'
gem 'mini_magick',             '3.8.0'
gem 'fog',                     '1.23.0'
gem 'will_paginate',           '3.0.7'
gem 'bootstrap-will_paginate', '0.0.10'
gem 'bootstrap-sass',          '3.2.0.0'
gem 'sass-rails',              '5.0.0.beta1'
gem 'uglifier',                '2.5.3'
gem 'coffee-rails',            '4.0.1'
gem 'jquery-rails',            '4.0.0.beta2'
gem 'turbolinks',              '2.3.0'
gem 'jbuilder',                '2.2.3'
gem 'rails-html-sanitizer',    '1.0.1'
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 :test do
  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
  gem 'unicorn',        '4.8.3'
end

尝试将unicorn gem添加到生产中。

我有同样的问题。原来是因为我使用的是ruby 1.9.3，默认情况下heroku使用的是2.x.解决方案是通过添加以下行在Gemfile中明确指定ruby版本：

ruby“1.9.3”

提交和推送后，它完美运行。

有关指定ruby版本的详细信息，请参阅https://devcenter.heroku.com/articles/ruby-versions。

Rails App无法推送到Heroku找不到rake-10.4.2
