Django遷移失敗heroku

我想部署一個Django（1.8）應用程序Heroku，運行時Python 3.4.2。該應用程序成功地運行（除未創建表的事實），但是當試圖運行執行syncdb我得到以下錯誤：Django遷移失敗heroku

Running `python manage.py syncdb` attached to terminal... up, run.5851

在你安裝的應用程序'authentication'？ – knbk

是的，身份驗證在已安裝的應用程序中。 – user3706162

在您的開發機器上，使用python manage.py makemigrations創建您的遷移。然後，假設您的遷移文件夾被推送到heroku，在heroku上運行python manage.py migrate而不是python manage.py syncdb。請參閱docs。

我遇到同樣的問題。我如何處理我虛擬環境中的django應用程序的遷移？也許這不是我的問題，我不確定。 – northben

嘗試heroku運行python manage.py migrate。這將遷移生產機器虛擬環境中的應用程序。 – mcastle

我，我用我們在我們的前綴「的Heroku運行」這就是它的本地服務器使用相同的命令來解決這個問題..

的如： -

python manage.py makemigrations

它將工作在我們當地但是Heroku的，像這樣的： -

heroku run python manage.py makemigrations

我哈德進入Heroku的機器慶典：

heroku run bash

然後進行makemigrations：

heroku run python manage.py makemigrations

最後，

heroku run python manage.py migrate
