Question

我正在从Python 2.7的Django 1.6.0迁移到Python 3.7的Django 2.1.5，并且在执行python manage.py makemigrations myapp时遇到错误。有人能给我一个解决的提示吗？我可能需要修改模型，但不确定应该从什么开始。

Migrations for 'model':
  model/migrations/0001_initial.py
    - Create model XXXX
    - Create model YYYY
    - Create model ZZZZ

如果需要，我将尝试提供有关该模型的更多详细信息。

在应用以下技术之前，请转储所有数据库。

删除所有迁移文件和文件夹，然后重新运行命令。

此外，比较Django文档中Django 1.6.0和2.1.5中使用的现有功能。
