使用手册
- pip install sqlacodegen
- sqlacodegen mysql://<数据库账号>:<数据库密码>@127.0.0.1:3306/<数据库名称> > models.py即可在当前目录生成models.py文件
报错Nomodulenamed’MySQLdb’
[root@59718da48394 Model]# /usr/local/python3/bin/sqlacodegen mysql://test:[email protected]:3306/testdb > EviewsModels.py

ModuleNotFoundError: No module named 'MySQLdb'
解决方案
- pip3 install pymysql
- vi /usr/local/python3/lib/python3.7/site-packages/sqlalchemy/dialects/mysql/mysqldb.py
- 找到dbapi(cls) 修改成如下
@classmethod
def dbapi(cls):
import pymysql
pymysql.install_as_MySQLdb()
return __import__('MySQLdb')
