这是我的堆栈信息：堆栈：bamboo-mri-1.9.2
当我尝试通过以下命令访问 heroku 控制台时：
heroku run -a pakrat script/rails console（pakrat 是我的应用程序名称）
我收到以下错误：/app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.1/lib/active_record/connection_adapters/postgresql_adapter.rb:1032:in initialize': could not translate host name "ec2-107-22-169-50.compute-1.amazonaws.com" to address: Name or service not known (PGError)
