ruby-on-rails - Heroku， bundler 因缺少依赖项而失败

Question

我最近在尝试在 Heroku 上部署 Rails 应用程序时遇到了麻烦。过去，我在 Heroku 上部署应用程序没有问题，但 Heroku 不再支持 ruby​​ 2.0.0。他们建议将 ruby "2.2.4" 添加到 Gemfile 中，这就是我所做的。我的 Gemfile 的开头如下:

source 'https://rubygems.org'
ruby "2.2.4"

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.0'
# Use pg as the database for Active Record
gem 'pg'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
...

所以，我在我的计算机上运行了版本 1.7.8 的bundle install，没有任何问题。我什至可以在生产模式下运行我的应用程序。但是，当我尝试在 Heroku 上部署该应用程序时，我得到以下信息:

非常感谢任何帮助。

我建议删除您的 Gemfile.lock，在本地再次运行 bundle install，将新的 Gemfile.lock 提交到您的 git 存储库，然后尝试您的 git push heroku master 再次。
