Heroku 上的 Rails MongoDb 项目无法启动

Question

大家好，我最近从 git hub git://github.com/barmstrong/ribbot.git 下载了一个开源代码“ribbot”，在设置好我的本地环境后，我能够让代码在我的本地机器上运行。我决定将 heroku 用于我的 web 基础解决方案并安装了 herokulabs。运行该站点时，我收到以下 heroku 日志错误：

我的 mongoid.yml 看起来像这样：

development:
  host: localhost
  database: ribbot_development

test:
  host: localhost
  database: ribbot_test

production:
  uri: <%= ENV['MONGOLAB_URI'] %>

端口 11211 是 memcached（可能）...所以也许您在本地使用 memcached，需要为 memcached 添加 heroku 插件。
