我被困了一个星期试图解决这个问题。我目前一直在关注在线讲座，但是我完全遵循了所有内容，而导师并没有给予任何帮助。每当我尝试推送到heroku时，我都会收到以下内容：
初始化存储库，完成。 计数对象：85，完成。 Delta压缩最多使用2个线程。 压缩对象：100％（76/76），完成。 书写对象：100％（85/85），27.36 KiB，完成。 总计85（delta 6），重用0（delta 0）

我已经尝试重建gem文件，删除gemfile.lock并运行bundle installer，遵循之前问题的解决方案，但我仍然收到此错误。
这是我目前的gemFile：
source 'https://rubygems.org'
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
group :development do
gem 'sqlite3'
gem 'rspec-rails', '2.6.1', :require => 'rspec-rails'
gem 'faker', '0.3.1'
end
group :test do
gem 'sqlite3'
gem 'rspec-rails', '2.6.1', :require => 'rpec-rails'
gem 'webrat', '0.7.1'
gem 'factory_girl_rails', '1.0'
gem 'turn', :require => false
end
group :production do
gem 'pg'
end
对此有何帮助？
答案 0 :(得分：4)
我会推荐一些东西：
1）按照here说明处理部署在Windows上生成的Ruby项目时出现的 Gemfile 问题。
2）在Gemfile中执行以下操作
group :test, :production do
gem 'pg'
end
group :development do
gem 'sqlite3'
end
这将从您的生产部署中删除sqlite3。使用它进行单元和集成测试，但使用PostgreSQL进行验收/功能测试，因为这是Heroku上选择的RDBMS。此外，每次仅引用您的宝石。
3）在Heroku上的部署环境中设置Hobby Dev version of the PostgreSQL add-on。
答案 1 :(得分：0)
You can't use SQLite on Heroku，你必须使用PostgreSQL。
您可以将其设置为在Heroku上使用PostgreSQL，但在开发中使用SQLite，在开发和生产环境中使用相同的数据库是一种很好的做法。
请注意，您多次列出gem 'sqlite3'次，包括开发组之外的sqlite次。这导致Heroku尝试安装它。
我的建议是完全删除{{1}} gem并将其全部切换到PostgreSQL。
答案 2 :(得分：0)
删除顶部gem sqlite3并在您的gemfile顶部添加ruby '2.0.0'
也在群组制作下添加gem 'rails_12factor'
