sqlalchemy-migrate ImportError：没有名为版本控制的模块

Question

我开始按照Miguel Grinberg的教程学习Flask。我在Flask应用程序中尝试运行迁移脚本时遇到此错误。但是，当我通过Python shell导入它时，它会起作用。更新SQLAlchemy和sqlalchemy-migrate软件包没有任何改动。任何人都有任何建议我如何解决它？

Traceback (most recent call last):

    from migrate.versioning import api
  File "/home/alexxmagpie/PycharmProjects/flasktest/migrate.py", line 3, in <module>
