Simple Signal Handling in Scrapy/Python giving error -

i'm trying catch closed signal in scrapy following code.

and error

traceback (most recent call last): signal.signal(scrapy.signals.spider_closed,scrapy_clean_up) typeerror: integer required

this code

import scrapy import signal,os  def scrapy_clean_up():     print "scrapy has closed!"  signal.signal(scrapy.signals.spider_closed,scrapy_clean_up)

am missing something?

the usual approach have scrapy signal handler use dispatcher:

from scrapy.xlib.pydispatch import dispatcher  dispatcher.connect(scrapy_clean_up, signal=scrapy.signals.spider_closed)
