当我尝试连接到数据库时，出现以下错误：
错误

AttributeError: module 'mysql.connector' has no attribute 'cursor_cext'

代码.py

import mysql
    import mysql.connector  
    from mysql.connector import errorcode 

    # MySQL database access parameters
    DB_PARAMS = {
        "user": "root",
        "password": "letmego",
        "host": "localhost",
        "port": 3306,
        "raise_on_warnings": False,
        "database": "playground"
    }

    def connect_db(
        params: dict,
        verbose: bool = True
    ) -> mysql.connector.connection_cext.CMySQLConnection:

        try:
        conn = mysql.connector.connect(**params)
    except mysql.connector.Error as err:
        print("[!] Function 'connect_db'")
        print(f"\t{err}\n")
        exit(1)
    else:
        if verbose:
            print(f"Database '{params['database']}' successfully connected.\n")
        return conn

if __name__ == '__main__':

    # connect to MySQL
    conn = connect_db(DB_PARAMS)

请告诉我我做错了什么。我还认为我已经导入了正确的依赖项。
