从外观上看，您的问题与您与mongodb. 我认为这可能就像确保您已启动MongoDB service. 看看下面的链接吧MongoDB Installation。取决于您使用的操作系统将取决于您需要执行哪些命令。但我完全相信你应该看看并确保你已经正确安装它并且服务正在运行，因为这是你问题的根源。

除此之外，还发现您必须在 Heroku 中安装 MongoHQ 插件。这会创建一个MONGOHQ_URLENV 变量，据说它是您的应用程序用来连接数据库的变量。

MongoHQ - Heroku 添加

添加 MongoHQ 的命令 -heroku addons:add mongohq

此外，您可能想查看以下MongoDB - Ruby以确保您database.yml的设置正确。您将在突出显示的Mongoid 2.x部分下看到。取决于您使用的版本将阻止您遵循的设置，因为当您进一步向下滚动时您会注意到有一个Mongoid 3.x部分。希望这可以帮助。
