我正在尝试将我的应用程序推送到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。

remote: Make sure that `gem install sqlite3 -v '1.3.10'` succeeds before bundling.

我对rails还很陌生，我不知道这里出了什么问题，因为Sqlite只用于开发，而不是生产。如果有人能帮我，我真的很感激，我已经试过搜索了，但找不出是什么原因造成的。谢谢
Heroku忽略开发宝石；然而，您拼错了开发，因此Heroku尝试安装gem。
group :devlopment, :test do
gem 'sqlite3'
end
将其更改为:development
我也有同样的错误。在我的Gemfile中有两次sqlite。一次在开发组中，一次在主列表中。将它从主列表中删除，效果非常好。
