python - argparse.ArgumentError：参数--skip-checks：冲突的选项字符串：--skip-checks

问题描述

我正在使用 django-tenant-schemas，当我尝试使用“migrate_schemas”命令时遇到错误。我在这里看到过类似的问题，但它们根本没有帮助。我在两个不同的应用程序上试过这个，但结果是一样的。有人知道如何解决这个问题吗？

解决方案

这是django-tenant-schemas. 从阅读 Django 文档看来，他们似乎忘记设置requires_system_checks为False.

我相信这个拉取请求会解决这个问题。

在合并此修复程序之前，您可以Django通过运行类似的东西降级到版本 2 来解决此问题

pip install "Django~=2.2"

或将tenant-schemas列表INSTALLED_APPS移至文件底部settings.py。
