无法运行“爬行报价”

Question

无法使scrapy教程起作用。

我正在尝试学习scrapy，但甚至无法运行教程。我试图在 python 3.7 & 3.5.5 中运行它，结果相同

导入scrapy

类 QuotesSpider(scrapy.Spider): name = "quotes"

def start_requests(self):

    urls = [

        'http://quotes.toscrape.com/page/1/',

        'http://quotes.toscrape.com/page/2/',

    ]

    for url in urls:

        yield scrapy.Request(url=url, callback=self.parse)

def parse(self, response):

    page = response.url.split("/")[-2]

    filename = 'quotes-%s.html' % page

    with open(filename, 'wb') as f:

        f.write(response.body)

    self.log('Saved file %s' % filename)

这似乎运行正常。至少它不会抛出任何错误。

当我在 Anaconda 提示窗口中运行“scrapy crawl quote”时，我得到了这个：
