Rails 4.1.5 ruby 2.1.2p95 MongoDB - 2.4.13Rails應用程序的Heroku錯誤

它在本地系統文件但是當deplying的Heroku它給出了問題

mongodb.yml

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
