在 Heroku 中部署时出现 Sinatra Datamapper 错误

Question

所以我尝试在 Heroku 上部署我的网络应用程序，但我不断收到这些错误：

app/vendor/bundle/ruby/2.1.0/gems/dm-core-1.2.1/lib/dm-core/adapters.rb:163:in require': cannot load such file -- dm-sqlite-adapter (LoadError)

我知道 Heroku 不能与 sqlite 一起使用，这就是我按照建议切换到 postgresql 的原因。但这只会让这更奇怪，因为我什至没有使用 sqlite。 :S

建议？

Answer 1

我认为 dm-sqlite-adapter 是从您的 Gemfile 引用的，或者是从代码中的其他地方引用的，可能是您配置数据映射器的地方。或者它可能是数据映射器 YAML 配置中的引用，如果你有的话。
