已经确保我安装了 pymysql 和 mysql-connector-python

我通读了解决方案Unable to install mysql connector for Python 3

是使用 pip install --allow-external mysql-connector-python mysql-connector-python ，但需要 pip 版本 8，它很旧，现在不能用，ps 讨论是 7 年前

The above exception was the direct cause of the following exception:

我确定 py 脚本部分，也就是 mydb 输入信息是正确的，我使用 simple .py script 可以连接并打印 MySQL 输出

    <py-script>
        import mysql.connector

        mydb = mysql.connector.connect(
          host="196.168.100.141",
          user="root",
          password="password123", 
          database="database_db",  
          auth_plugin='mysql_native_password'
        )
                        
        mycursor = mydb.cursor()
        mycursor.execute("SELECT row_01 FROM database")                       
                                                 
        myresult = mycursor.fetchall()
        
        list_01 = []
        
        for row in myresult:
          temp_val = row[0]
          list_01.append(temp_val)
    </py-script>

您使用的是PyScript框架，其中Python安装在第三方服务的服务器端，与您本地的Python安装无关。

根据 PyScript 的 Importing the needed libraries 文档，您应该使用 py-config 标记声明您希望安装的库，您有一些标记，但是使用包名称 mysql-connector-python，而不是模块名称 mysql.connector：

packages = ["pymysql", "mysql-connector-python"]

这会运行，但不会从服务器端连接到 IP 地址为 196.168.100.141 的数据库，因为它可能仅在您的局域网中可用：
