嗨，我正在尝试升级到wagtail 2.0。 我已经处理了一系列错误但我无法通过迁移时发生的错误：

任何帮助非常感谢

谢谢

完全控制台错误：

通过wagtail v2.0.1兼容性文档

Wagtail supports Django 1.11.x and 2.0 on Python 3.4, 3.5 and 3.6. Supported database backends are PostgreSQL, MySQL and SQLite.

但你尝试使用Django> = 1.11
并通过doc django ForeignKey获得版本1.11

(on_delete isn’t actually required, but not providing it gives a deprecation warning. It will be required in Django 2.0.)
