运行“scrapy crawl quotes”和“scrapy genspider quotes qoutes.toscrape.com”命令时出错

Question

我按照教程制作了一个网络爬虫。

概述：-

1. 创建虚拟环境(virtualenv .)
2. 激活它 (.\Scripts\activate)
3. scrapy.cfg 所在的目录(cd quotetutorial)
4. 创建了quotes_spider.py
5. 执行 scrapy crawl quotes 和 scrapy genspider quotes quotes.toscrape.com 并得到相同的错误

spider_quotes.py 文件内容：-

class QuoteSpider(scrapy.Spider):#inheriting from class scrapy from spider
    name='quotes'
    start_urls=['https://quotes.toscrape.com/']
    def parse(self,response)
        title=response.css('title').extract()
        yield {'titletext': title} 

即使在包含scrapy.cfg 文件的文件夹中运行scrapy crawl 引号后，我也会收到此错误。 error message

Answer 1

您忘记在方法定义中添加: 符号：

class QuoteSpider(scrapy.Spider):#inheriting from class scrapy from spider
    name='quotes'
    start_urls=['https://quotes.toscrape.com/']
    def parse(self,response): # <- : added
        title=response.css('title').extract()
        yield {'titletext': title}
