Ruby on rails Heroku-We'；I’很抱歉，出了点问题

我在我的命令上运行了

heroku run rake db:migrate

，但它仍然给我这个错误。 有人能解释一下吗

这是我的heroku日志：

错误是否也在本地发生，还是仅在Heroku上发生？还有，这是完整的日志还是更多的日志？我没发现那条线索有什么错误，只有在heroku身上。还有更多，但我也看不到任何错误……你在跟踪中看到类似于heroku[router]：at=error的东西了吗？另外，在部署到Heroku之前，您是否在本地预编译您的资产，或者在

production.rb

中是否有

config.assets.compile=true

？是否有

Procfile

？@mmichael是的，我将其视为true。我没有看到heroku[路由器]：at=错误。
