Question

我在heroku上有一个rails应用程序，我无法运行最新的数据库更改。正在运行heroku run rake db:migrate给我

Running `rake db:migrate` attached to terminal... up, run.3167
!    Heroku client internal error.
!    Search for help at: https://help.heroku.com

尝试在后台运行它：

heroku run:detached rake db:migrate

Answer 2

运行后

    heroku run:detached rake db:migrate

我能够成功运行

    heroku run rake db:migrate

Heroku rake db：migrate导致错误R13（附加错误） - ＆gt;无法附加到进程
