我想部署一个Django(1.8)应用程序Heroku,运行时Python 3.4.2。该应用程序成功地运行(除未创建表的事实),但是当试图运行执行syncdb我得到以下错误:Django迁移失败heroku

在您的开发机器上,使用python manage.py makemigrations创建您的迁移。然后,假设您的迁移文件夹被推送到heroku,在heroku上运行python manage.py migrate而不是python manage.py syncdb。请参阅docs

我遇到同样的问题。我如何处理我虚拟环境中的django应用程序的迁移?也许这不是我的问题,我不确定。 – northben

尝试heroku运行python manage.py migrate。这将迁移生产机器虚拟环境中的应用程序。 – mcastle

我,我用我们在我们的前缀“的Heroku运行”这就是它的本地服务器使用相同的命令来解决这个问题..

的如: -

python manage.py makemigrations 

它将工作在我们当地但是Heroku的,像这样的: -

heroku run python manage.py makemigrations

我哈德进入Heroku的机器庆典

heroku run bash

然后进行makemigrations

heroku run python manage.py makemigrations 

最后,

heroku run python manage.py migrate
