Heroku與紅寶石在軌道上和Mongoid

Question

我正在與Mongoid一起進行ROR項目。 運行Rails脫機服務器時，該應用程序運行正常，但是當我在Heroku上部署它時，會拋出此錯誤

2016-02-03T16:34:08.405268+00:00 heroku[web.1]: Process exited with status 1

我不是在使用ActiveRecords，而是在使用Mongoid，因此請向我建議解決此問題的任何方法。

提前致謝

導致應用程序崩潰的原因有很多，例如heroku服務器缺少某些需要在應用程序中運行的gem。 采用
$ heroku日志--tail
查看確切在heroku服務器中發生的情況。
