Question

我使用pip在python中安装了mysql插件和lib，当我在pycharm中使用它时它正在工作。但是如果我尝试使用命令python和文件名使用cmd提示执行相同操作，则会抛出错误，说明＆＃34;没有模块名称＆＃39; mysql＆＃39;＆＃34; 。所以我也在python34目录的libs中检查了它，我可以在那里看到可用的包。我无法弄清楚问题是什么，以及如何克服这个问题。这是我的代码，它在pycharm中正常工作但如果我尝试使用cmd提示符执行它会抛出错误

import mysql.connector
from mysql.connector import errorcode

class DBConnection:
    global connect
    global config

    def __init__(self):
        "Setting the paramenter to set the DB"
        config = {
            'user': 'root',
            'password': 'VMware@1234',
            'host': '127.0.0.1',
            'database': 'super_nova',
            'raise_on_warnings': True,
        };

    def connectToDB(self):
        "connection of the database is done here"
        try:
            #connect = mysql.connector.connect(**config)
            connect = mysql.connector.connect(user='root', password='VMware@1234',host='127.0.0.1' ,database='super_nova')
            return connect
        except mysql.connector.Error as err:
            if err.errno == errorcode.ER_ACCESS_DENIED_ERROR:
                print("Something is wrong with your user name or password")
            elif err.errno == errorcode.ER_BAD_DB_ERROR:
                print("Database does not exist")
            else:
                print(err)


    def closeDB(self,connection):
        "Make sures the connections is closed"
        connection.close()

from com.test import test2

def fun():
    test2.DBConnection().connectToDB()



if __name__ == '__main__':
    fun()

错误信息是：

from com.test import test2   File "C:\Users\nkumarn\TestPythons\com\test\test2.py", line 1, in <module>
import mysql.connector ImportError: No module named 'mysql'

请帮我解决一下。感谢您抽出宝贵时间阅读本文。

没有模块名称＆＃39; mysql＆＃39;
