argparse.ArgumentError: argument --skip-checks: conflicting option string: --skip-checks

Question

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？

Answer 1

这是 django-tenant-schemas 中的错误。通过阅读 Django 文档，他们似乎忘记将 requires_system_checks 设置为 False。

我相信 pull request 会解决问题。

在合并此修复程序之前，您可以通过运行将 Django 降级到版本 2 来解决此问题，例如

pip install "Django~=2.2"

或将 INSTALLED_APPS 列表中的 tenant-schemas 移动到 settings.py 文件的底部。

argparse.ArgumentError: argument --skip-checks: conflicting option string: --skip-checks

python

django
