Scrapy-Python无法将数据插入Mac OS上的mySQL工作台：延迟中的未处理错误

我想从一个网站上抓取一个数据，并将其插入mySQL工作台

我的话是这样的：

管道.py

# Define your item pipelines here
#
# Don't forget to add your pipeline to the ITEM_PIPELINES setting
# See: https://docs.scrapy.org/en/latest/topics/item-pipeline.html


# useful for handling different item types with a single interface
from itemadapter import ItemAdapter

import mysql.connector
import mysql


class MojulePipeline(object):
    def __init__(self):
        self.create_connection()
        self.create_table()

    def create_connection(self):
        self.conn = mysql.connector.connect(
            host = 'localhost',
            user = 'root',
            passwd = 'asdfasdf',
            database = 'refq'
        )
        self.curr = self.conn.cursor()

    def create_table(self):
        # self.curr.execute("DROP TABLE IF EXISTS refqt")
        self.curr.execute("""create table refqt(
                        subtitle text,
                        question text,
                        canswer text,
                        wanswer1 text,
                        wanswer2 text,
                        wanswer3 text,
                        )""")
    
    def process_item(self, item, spider):
        self.store_db(item)
        return item

    def store_db(self,item):
        self.curr.execute("""insert into refqt values (%s,%s,%s,%s,%s,%s)""", (
            item['subtitle'][0],
            item['question'][0],
            item['canswer'][0],
            item['wanswer1'][0],
            item['wanswer2'][0],
            item['wanswer3'][0],
        ))

        self.conn.commit()

然后是items.py 我的蜘蛛 我能够获取所有数据，并能看到输出。但是当我尝试插入时，它显示了很多错误

错误如下：
