我正在创建一个网络爬虫，从一个网站捕获数据，然后将其插入我的数据库。我正在使用scrapy和mysql。我创建了以下代码：
管道.py：

class MySQLStorePipeline(object):
 def __init__(self):
 self.conn = MySQLdb.connect(host ='localhost', user ='root', passwd ='', db ='imoveis', charset="utf8", use_unicode=True)
 self.cursor = self.conn.cursor()

 def process_item(self, item, spider):    
   try:
    self.cursor.execute("""INSERT INTO imovel (Titulo, Tipo_Negocio, Preco, Localizacao, Tipo_Imovel, Condicao, Numero_Divisoes, Numero_Quartos, Numero_Casas_Banho, Certificado_Energetico, Ano_Construcao, Area_Util, Area_Bruta, Piso)  
                VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)""", 
               (item['Titulo'], 
                item['Tipo_Negocio'],
                item['Preco'],
                item['Localizacao'],
                item['Tipo_Imovel'],
                item['Condicao'],
                item['Numero_Divisoes'],
                item['Numero_Quartos'],
                item['Numero_Casas_Banho'],
                item['Certificado_Energetico'],
                item['Ano_Construcao'],
                item['Area_Util'],
                item['Area_Bruta'],
                item['Piso']))            
    self.conn.commit()

except MySQLdb.Error as e:
    print('Error %d: %s' % (e.args[0], e.args[1]))
    sys.exit(1)

return item

设置.py：

BOT_NAME = 'novo'

SPIDER_MODULES = ['novo.spiders']
NEWSPIDER_MODULE = 'novo.spiders'

FEED_EXPORT_ENCODING = 'utf-8'

ITEM_PIPELINES = {
  'novo.pipelines.MySQLStorePipeline' : 300
}

ROBOTSTXT_OBEY = True

爬虫.py：

class SapoSpider(scrapy.Spider):
 name = "imoveis"
 allowed_domains = ["maisconsultores.pt"]
 start_urls = ["https://www.maisconsultores.pt/properties?page=%d&s=eedce" % i for i in range(23)]

 def parse(self,response):
   subpage_links = []

   for i in response.css('div.item.col-sm-4'):
    youritem = {
    'Titulo':i.css('div[class=image] h3::text').extract(),
    'Tipo_Negocio':i.css('div.price::text').re('[^\t\n\r\a]+'),
    }

    subpage_link = i.css('div[class=image] a::attr(href)').extract_first()
    full_url = response.urljoin(subpage_link)
    yield scrapy.Request(full_url, callback=self.parse_subpage, meta={'item':youritem})

def parse_subpage(self,response):
    youritem = response.meta.get('item')
    youritem['Tipo_Imovel'] = response.xpath('//ul[@class="amenities"]//li[1]/text()').extract()
    youritem['Condicao'] = response.xpath('//ul[@class="amenities"]//li[2]/text()').extract()
    yield youritem

运行scrapy时出现的错误如下：

_mysql_exceptions.OperationalError: (1241, 'Operand should contain 1 column(s)')

我真的不知道或看不到我在这里错过了什么。如果你们能帮我，我会非常感激的。
