$ heroku db:pull
它說
Loaded Taps v0.3.24 Auto-detected local database: mysql2://root:[email protected]/app?encoding=utf8 Warning: Data in the database 'mysql2://root:[email protected]/app?encoding=utf8' will be overwritten and will not be recoverable. ! WARNING: Destructive Action ! This command will affect the app: heroku-app-9999 ! To proceed, type "heroku-app-9999" or re-run this command with --return heroku-app-9999
，所以我跑
$ cryptic-harbor-6329
然後我得到這樣的響應：
! <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
! <html>

! <title>Application Error</title></head>
! </head>
! <body>
! <iframe src="//s3.amazonaws.com/heroku_pages/error.html">

! </iframe>
! </body>
! </html>
我已經拉了很多次，並推送到不同的應用程序heroku。我從未收到這個錯誤。這意味着什麼劑量？
