heroku Error R10

Question

I created a sample app called stock portfolio manager 

https://github.com/rohanmoitra/foliomanage，并将其部署在Heroku上。但是，每当我尝试运行Heroku Rake DB：将其迁移到以下错误时。

2012-10-22T22:28:35+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process
 failed to bind to $PORT within 60 seconds of launch
2012-10-22T22:28:35+00:00 heroku[web.1]: Stopping process with SIGKILL
2012-10-22T22:28:36+00:00 heroku[web.1]: Process exited with status 137
2012-10-22T22:28:36+00:00 heroku[web.1]: State changed from starting to crashed
Has anyone encountered this error before? Any help would be deeply appreciated

Answer 1

您不应该在Heroku靴子上进行迁移。后者限制为60秒。作为耙子任务分别运行迁移。如果您真的真的想这样做，则必须在启动超时（https://github.com/dblock/heroku-forward）上工作。
