导轨 4.1.5 红宝石 2.1.2p95 MongoDB - 2.4.13

它在本地系统中工作文件，但是在部署 heroku 时它出错了

production:
  sessions:
    default:
      uri: <%= ENV['MONGOHQ_URL'] %>
      options:
        consistency: :strong
        max_retries_on_connection_failure: 20
        persist_in_safe_mode: true
        skip_version_check: true
