Python 属性错误：'；CSV管道'；对象没有属性'；spider_关闭'；

我按照

http://stackoverflow.com/questions/20753358/how-can-i-use-the-fields-to-export-attribute-in-baseitemexporter-to-order-my-scr/20758558#20758558

并尝试按顺序导出项目字段。但终端只是输出

crawler.signals.connect（pipeline.spider\u关闭，signals.spider\u关闭）
AttributeError:“CSVPipeline”对象没有属性“spider\u closed”

这是我的

管道.py

from scrapy import signals
from scrapy.contrib.exporter import CsvItemExporter

class CSVPipeline(object):

    def __init__(self):
        self.files = {}

    @classmethod
    def from_crawler(cls, crawler):
        pipeline = cls()
        crawler.signals.connect(pipeline.spider_opened, signals.spider_opened)
        crawler.signals.connect(pipeline.spider_closed, signals.spider_closed)
        return pipeline

    def spider_opened(self, spider):
        file = open('%s_items.csv' % spider.name, 'w+b')
        self.files[spider] = file
        self.exporter = CsvItemExporter(file)
        self.exporter.fields_to_export = ['c_name','c_employeeN','c_website','c_street','c_state_zip_code','c_country','p1c_name','p1c_role','p1c_phoneNumber','p1c_email','p2c_name','p2c_role','p2c_phoneNumber','p2c_email','p3c_name','p3c_role','p3c_phoneNumber','p3c_email','p1h_name','p1h_role','p1h_phoneNumber','p1h_email','p2h_name','p2h_role','p2h_phoneNumber','p2h_email','p3h_name','p3h_role','p3h_phoneNumber','p3h_email','p1f_name','p1f_role','p1f_phoneNumber','p1f_email','p2f_name','p2f_role','p2f_phoneNumber','p2f_email']
        self.exporter.start_exporting()

    def spider_cloesd(self, spider):
        self.exporter.finish_exporting()
        file = self.files.pop(spider)
        file.close()

    def process_item(self, item, spider):
        self.exporter.export_item(item)
        return item

我在我的

设置.py中添加了
ITEM_PIPELINES={'zoominfo_test.PIPELINES.CSVPipeline'：300，}

我只是不知道发生了什么。如果有人能给我一个提示，我将不胜感激。谢谢
 很明显，方法名中有输入错误

def spider_cloesd(self, spider):
    self.exporter.finish_exporting()
    file = self.files.pop(spider)
    file.close()
