我不断收到heroku的错误。这是一个使用 Mongoid 的 Sinatra 应用程序。尽管我也在那里托管了一个 Rails 应用程序，但它不会导致任何错误，尽管它们具有完全相同的 mongoid.yml 文件。

这是heroku的日志显示异常

错误是应用程序无法连接到它期望运行的本地 mongo 实例。

如果您认为日志消息很长，那么您还没有看到 Java Spring 自动装配异常 =) 虽然在这种情况下，最上面的错误消息足以确定问题。

我刚刚让 Mongo HQ 在 Heroku 上使用我的 Rails 应用程序，所以我的建议是：

在您的项目目录中运行heroku config以检查您是否已定义 RACK_ENV=production 并且 MONGOHQ_URL 已由 Heroku 定义。

如果 MONGOHQ_URL 没有在 Heroku 上定义为环境变量，很可能你还没有跑过去heroku addons:add mongohq:sandbox 告诉 Heroku 你想要一个 Mongo HQ 实例。

如果 RACK_ENV=production 未定义，只需添加： heroku config:add RACK_ENV=production

在此之后，重新启动您的应用程序，heroku restart它应该可以工作。

Rails 应用程序（而不是 Sinatra）的仅供参考，RACK_ENV 变为 RAILS_ENV。
