【问题描述】:
我正在尝试将 Django (1.8) 应用程序部署到 Heroku,运行时 Python 3.4.2。该应用程序成功运行(除了未创建表的事实),但在尝试运行 syncdb 时出现以下错误:
Running `python manage.py syncdb` attached to terminal... up, run.5851
/app/.heroku/python/lib/python3.4/site-packages/django/core/management
/commands/syncdb.py:24: RemovedInDjango19Warning: The syncdb command
will be removed in Django 1.9
warnings.warn("The syncdb command will be removed in Django 1.9", RemovedInDjango19Warning)

During handling of the above exception, another exception occurred:

我正在使用 sqlite。
【问题讨论】:
-
您安装的应用中有
authentication吗? -
是的,身份验证在已安装的应用程序中。
