ruby-on-rails – 不能heroku运行rake db通过我的应用程序迁移

这是我第一次遇到这样的错误：

Running `rake db:migrate` attached to terminal... up,run.8524
 !    Heroku client internal error.
 !    Search for help at: https://help.heroku.com
 !    Or report a bug at: https://github.com/heroku/heroku/issues/new

    Error:       Operation timed out - connect(2) (Errno::ETIMEDOUT)

    Command:     heroku run rake db:migrate --app oppcis
    Version:     heroku-toolbelt/2.35.0 (x86_64-darwin10.8.0) ruby/1.9.3

我已经出了一段时间在使用英雄…而且大回来之后,我遇到了这个错误.

我现在已经过时了,现在Heroku的消息.

我希望有人能给我一个建议,解决方案或涉及的问题.

谢谢.

解决方法

尝试运行它在“背景”

heroku run:detached rake db:migrate

您也可以尝试heroku troubleshooting,因为它似乎是一个连接问题.

heroku run rails console
telnet rendezvous.runtime.heroku.com 5000

如果它不起作用,你可能有一个防火墙阻止你连接到heroku.
