Ошибка при запуске паука в Scrapy.Как победить?

Есть паук:

# -*- coding: utf-8 -*-



from quoka.items import QuokaItem
from scrapy.spiders import CrawlSpider, Rule
from scrapy.linkextractors import LinkExtractor
from scrapy.loader.processors import TakeFirst
from scrapy.loader import XPathItemLoader
from scrapy.selector import HtmlXPathSelector

class QuokaLoader(XPathItemLoader):
    default_output_processor = TakeFirst()


class QuokaSpider(CrawlSpider):

    name = "quoka"
    allowed_domains = ["quoka.de"]
    start_urls = ["http://www.quoka.de/immobilien/bueros-gewerbeflaechen/"]

    rules = (
             Rule(LinkExtractor(allow=('kleinanzeigen/cat_27_2710_ct_0_page_')), follow=True),
             Rule(LinkExtractor(allow=('immobilien/bueros-gewerbeflaechen/')), callback='parse_item'),
             )

    def parse_item(self, response):
        hxs = HtmlXPathSelector(response)
        l = QuokaLoader(QuokaItem(), hxs)

        #
        l.add_xpath('date',response.xpath("/html/body/div[3]/div[2]/div[1]/main/div[8]/div/div[2]/strong/span/text()").extract())
        l.add_xpath('cost',response.xpath("/html/body/div[3]/div[2]/div[1]/main/div[8]/div/div[3]/div[2]/div[2]/text()").extract())
       # l.add_value('url', response.url)

        return l.load_item()

командой sudo scrapy crawl quoka_spider.py запускаю его.
После этого выводятся следующие ошибки:

During handling of the above exception, another exception occurred:

Пробовал удалять и заново устанавливать Scrapy, но результат тот же
