Arbeiten Sie nicht Scrapy Spinne

Question

ich eine Website analysieren, und ich habe eine Spinne:

# -*- 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() 

Geben Sie den Befehl: sudo scrapy crawl quoka_spider.py

Aber ich habe mystische Fehler:

Ich benutze Ubuntu 16.04, Python 3.5. Installieren Sie scraby pip3 installieren Scraby. Ich installiere Scraby neu, habe aber keinen Erfolg. Wie funktioniert das?

sudo scrapy crawl quoka_spider.py

Sie sollten den Namen Eigentum Ihrer Spinne,
Statt folgenden verwenden

scrapy crawl quoka
