cannot import name 'util' from 'sqlalchemy'

Question

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
import pymysql

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql+pymysql://root@localhost:3306/wet'
db = SQLAlchemy(app)



example = example(data='have a try')
db.session.add(example)
db.session.commit()

一直报错：

求问这是为啥呀？我是按照视频一点点学flask，该装的包都装了

Answer 1

注意文件名不能与包同名， 注意查看一下，如果同名修改一下名字就可以了。
