我有一个带有两个遥控器的 heroku 应用程序：登台和生产。到目前为止，我对此没有任何问题。
今天我已成功推送到我的生产应用程序，但在尝试推送/获取我的暂存应用程序时出现以下错误。
! Heroku Git error, please try again shortly.
! See http://status.heroku.com for current Heroku platform status.
! If the problem persists, please contact http://support.heroku.com.
fatal: The remote end hung up unexpectedly
登台应用程序工作正常。它响应请求，我可以成功地做一些事情heroku run console --remote=staging。
我尝试git push -f staging master并得到了同样的错误。我所有的 heroku 应用程序都在运行，但由于某种原因，我无法推送到这个登台应用程序。
这是我跑步时得到的heroku run rake about --remote=staging
