我正在尝试将我的应用推向Heroku。我在开发中使用了sqlite gem，在生产中使用了pg gem，但我仍然得到：
Detected sqlite3 gem which is not supported on Heroku.
错误。

我对rails非常陌生，因为Sqlite仅用于开发而非生产，所以我无法解决这里出现的问题。如果有人能帮助我，我真的很感激，我已经尝试过搜索并且无法解决导致这种情况的原因。谢谢！

Heroku忽略了开发宝石;但是，你错误的开发，因此Heroku试图安装gem。
group :devlopment, :test do
gem 'sqlite3'
end
将其更改为:development

我有同样的错误。我的Gemfile中有两次sqlite。一旦进入开发组，一次进入主列表。从主列表中删除它，效果很好。
