Question

这是我的代码：

from example1 import db, Puppy

db.create_all()

sam = Puppy('Sammy', 3)
frank = Puppy ('Frankie',2)

print (sam.id)
print (frank.id)

db.session.add_all([sam,frank])

db.session.commit()

print(sam.id)
print(frank.id)

这是我的错误：

我该如何解决？

Answer 1

您必须更新SQLAlchemy

pip uninstall SQLAlchemy
pip install SQLAlchemy==1.3.6

AttributeError：模块“时间”没有属性“时钟”
