AttributeError： 'CSVPipeline'オブジェクトに 'spider_closed'属性がありません

Question

http://stackoverflow.com/questions/20753358/how-can-i-use-the-fields-to-export-attribute-in-baseitemexporter-to-order-my-scr/20758558#20758558の指示に従って、アイテムのフィールドを順番にエクスポートしようとしました。しかし crawler.signals.connect(pipeline.spider_closed, signals.spider_closed) AttributeError: 'CSVPipeline' object has no attribute 'spider_closed'

だけ出力端子をここに私pipelines.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 

だと私はちょうど何が起こったのかわからない私のsetting.py

でITEM_PIPELINES = {'zoominfo_test.pipelines.CSVPipeline': 300,}を追加しました。誰かが私にヒントを与えることができたと非常に感謝します。ありがとう！

あなたは明らかメソッド名にタイプミスがあり

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