显然， sqlite3 gem 是这里的问题。奇怪的是，它没有作为依赖项包含在我的 Gemfile 或 Gemfile.lock 中。
我的 gemfile 看起来像这样：
source 'http://rubygems.org'
gem 'rails', '3.1.0'
gem 'pg'
gem 'thin'
gem 'authlogic', '3.1.3'
gem 'twilio-ruby'
gem 'heroku'
gem 'activeadmin', :git => 'https://github.com/gregbell/active_admin.git'
gem 'stripe', :git => 'https://github.com/stripe/stripe-ruby'
gem 'faye'
group :assets do
gem 'less'
gem 'bourbon'
gem 'therubyracer'
gem 'sass-rails'
gem 'coffee-rails'
gem 'uglifier'
end
这里有几件事很突出。Heroku 安装的 authlogic gem 不是 Gemfile 中指定的。我怀疑 authlogic gem 的唯一原因是因为它将 sqlite3 列为开发依赖项。不过这应该没关系。
当我在本地机器上运行 Heroku 输出中列出的确切命令时，没有安装 sqlite3 gem。
我尝试了许多在 StackOverflow 和其他地方找到的建议，例如删除 Gemfile.lock 文件并再次运行捆绑程序。这些都没有奏效。Heroku 仍然安装了错误版本的 authlogic 并尝试安装 sqlite3。
如何让 Heroku 停止尝试安装 sqlite3 gem？
非常感谢您的帮助！
