Failed ruby push to heroku

Question

我正在尝试'git push heroku master'，但收到:

安装sqlite3(1.3.9)时发生错误，Bundler无法继续。

结果，我被告知推送被拒绝，因为Ruby应用程序编译失败。

这里是Gemfile:

source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.4'
# Use sqlite3 as the database for Active Record
group :development, :test do
  gem 'sqlite3'
end
group :production do
  gem 'pg'
  gem 'rails_12factor'
end
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.2'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'
group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', require: false
end
# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'
# Use unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano', group: :development
# Use debugger
# gem 'debugger', group: [:development, :test]

知道为什么会出现这个错误吗?今晚大部分时间我都无法让它工作。

不能在Heroku上使用sqlite

如果你已经从Gemfile中删除了gem 'sqlite3行，并且在部署到Heroku时仍然出现错误，那么很可能你正在使用的另一个gem有sqlite3作为依赖项。要帮助找到这个依赖的来源，请查看您的Gemfile。锁定sqlite3。找到将sqlite3作为依赖项的gem并将其从Gemfile中删除。一旦你完成了这些，运行bundle install并确保在你的Gemfile.lock.

中不再存在sqlite3。
