带有 mysql 连接器的 python 中的回溯错误

Question

我收到以下错误。 我对 sql 和或 python 一点也不擅长，所以我会很感激一个简化的答案。 ：

Traceback (most recent call last):
  File "C:\Users\samra\Desktop\folder\1.py", line 2, in <module>
    con = sq.connect(host="localhost",user="root",passwd="root",database="bank")
  File "C:\Users\samra\AppData\Local\Programs\Python\Python39\lib\site-packages\mysql\connector\__init__.py", line 179, in connect
    return MySQLConnection(*args, **kwargs)

    raise errors.NotSupportedError(
mysql.connector.errors.NotSupportedError: Authentication plugin 'caching_sha2_password' is not supported

我的代码是：

import mysql.connector as sq
con = sq.connect(host="localhost",user="root",password="root",database="bank")
def openacc():
    n=input("Enter name : ")
    ac=input("Enter account no. : ")
    db=input("Enter D.O.B : ")
    p=input("Enter phone number : ")
    ad=input("Enter Address : ")
    ob=int(input("Enter opening balance : "))
    data1=input(n,ac,db,p,ad,ob)
    data2=input(n,ac,ob)
    sql1="insert into account value(%s,%s,%s,%s,%s,%s)"
    sql2="insert into account value(%s,%s,%s,%s,%s,%s)"
    c=con.cursor()
    c.execute(sql1,data1)
    c.execute(sql2,data2)
    con.commit()
    print("data entered successfully")
    main()

我已经检查过，我的数据库的密码和用户是正确的，因此不应该有错误。 请帮忙。

在 MySQL 8.0 中，caching_sha2_password 是默认的身份验证插件，而不是 mysql_native_password。 尝试这个

con = sq.connect(host="localhost",user="root",password="root",database="bank",auth_plugin='mysql_native_password')

在MYSQL CLI中输入

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '{Password}';
