Python 从Wagtail 2.7.1迁移到2.7.4的问题

我不得不将Wagtail和Django一起升级以获得一些安全更新。当我的本地数据库崩溃并重新运行迁移时，我会出现以下错误。我的后端是Postgres

Django版本：2.2.13 Postrges版本：9.4

我似乎不明白为什么会发生这种情况，以及如何解决它。据我所知，不应该有任何问题，因为这是一个全新的安装（本地），运行迁移时数据库中没有模式或数据

任何帮助都将不胜感激。谢谢。

您似乎错误地将Django更新为第3版。*as

Django 3.0，在中也可见

Posgresql9.5有一个新的ON-CONFLICT子句，在以前的PostgreSQL版本中不可用，Django利用了它

---

请记住，PostgreSQL 9.4不再受PostgreSQL团队的支持，应该更新

什么是Django版本，Postgres versionI更新了我的问题，对此表示抱歉。但是，django版本：2.2.13 Postgres版本：9.4您确定吗？因为答案中说明的原因，看起来您已经将其更新为3.0了
