Question

我正在尝试使用Alembic进行新的修订。为此，我导航到alembic目录并输入：

alembic revision -m "update my api"

输出：

AttributeError: 'module' object has no attribute 'suite'

我按照Alembic: alembic revision says Import Error的建议将PATH / to / myapi导出到$ PYTHONPATH变量，但总是遇到同样的错误。有帮助吗？谢谢

Alembic：AttributeError：'module'对象没有属性'suite'
