我正在尝试将我的应用程序放在Heroku上，但是当我运行heroku rake db：migrate时，我得到以下错误。似乎event_calendar gem导致了问题，但问题是，我已经卸载了它。 gemfile或gemfile.lock中没有对它的引用，并且它没有显示在gem列表中。尝试gem list -d event_calendar只返回 * LOCAL GEMS * ，据我所知，所有与event_calendar相关的文件都已被删除。为什么Heroku似乎还有问题？

答案 0 :(得分：0)
所以我在等待期间向Heroku发送了一张支持票，结果发现Gemfile没有被推送到Heroku，我使用git的方式出现了问题，并且推出了旧版本。一旦我正确地更新了我的git分支并推送到Heroku就可以了。
