MySQL 未通过 python 连接

Question

MySQL 未连接并显示错误

我通过pip安装mysql.connector包

这是代码

import mysql.connector
connection = mysql.connector.connect(host = "localhost", user = "root",passwd = "268455")
print(connection)

这是我收到的错误

我搜索了很多网站，我都用同样的方法做了，但仍然出现错误

Answer 1

您必须包含要与之连接的数据库，并且消息不能像您使用的那样。

一个例子：

def MySQLConnect(usernameStr, passwordStr, hostStr, databaseStr, conPrint = True):
    #ESTABLISH THE CONNECTION WITH THE DATABASE
    try:
        con = mysql.connector.connect(
            user = usernameStr,
            password = passwordStr,
            host = hostStr,
            database = databaseStr)

        if conPrint: print('Connection established successfully with the database')
        return con
    except Error:
        print(Error)

Answer 2

问题已解决。我安装了 mysql-connector 包，而我需要安装 mysql-connector-python 包。首先卸载 mysql-connector 软件包，然后安装 mysql-connector-python 软件包。

MySQL 未通过 python 连接

MySQL is not connecting through python

mysql

mysql-python
