Bundler每次都保持安装sqlite3，但我没有在我的项目中使用它。我选择了Postgres，但无法将其部署到Heroku。 Bundler就是这个原因。为什么会这样？我该怎么办？
我试图为此制作单独的gemset。我清除并重新安装了所有宝石。但每次sqlite来到我的“捆绑安装”日志：
.......
Using sqlite3 (1.3.4)
Using sqlite3-ruby (1.3.3)
Using taps (0.3.23)
Using thin (1.2.11)
Using turn (0.8.2)
Using uglifier (1.0.3)
Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
我的Gemfile：
source 'http://rubygems.org'
gem 'rails', '3.1.0'
gem "jquery-rails"
gem 'sorcery'
gem 'simple_form'
gem 'cocoon'
gem 'thin'
gem 'heroku'
gem 'taps'
gem 'pg'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"
gem 'uglifier'
end
group :development do
gem "cucumber-rails"
gem "capybara"
gem "rspec-rails", ">= 2.0.1"
end
group :test do
gem 'turn', :require => false
gem "cucumber-rails"
gem "capybara"
gem "rspec-rails", ">= 2.0.1"
gem "database_cleaner"
gem "factory_girl_rails"
end
帮帮忙，怎么了？
更新： 添加了Gemfile.lock：

答案 0 :(得分：3)
（即使你已经弄明白了，我也会把它放在这里，因为某些原因人们不会阅读这些评论）
你在Gemfile中需要的'taps'宝石（http://rubygems.org/gems/taps）对'sqlite3-ruby'宝石有一定的依赖性。
通过查看Gemfile.lock文件，您可以通常查找奇怪的依赖关系，正如您在此处所看到的那样......
taps (0.3.23)
rack (>= 1.0.1)
rest-client (< 1.7.0, >= 1.4.0)
sequel (~> 3.20.0)
sinatra (~> 1.0.0)
sqlite3-ruby (~> 1.2)
每个gem都将列出其运行时依赖性以及它所需的版本。
