我正在学习用 scrapy 进行 python 抓取。我做了和教程教的完全一样的事情。但我得到了一个错误。请帮忙！

我的Python代码：

import scrapy


class BookSpider(scrapy.Spider):
    name = "books"
    allowed_domains = ["books.toscrape.com"]
    start_urls = ["https://books.toscrape.com"]

    def parse(self, response):
        books = response.css("article.product_pod")
                             
        for book in books:
            yield{
                "name":book.css("h3 a::text").get(),
                "price":book.css(".product_price .price_color::text").get(),
                "url": book.css("h3 a").attrib["href"],
            }

终端显示

import scrapy


class BookSpider(scrapy.Spider):
    name = "books"
    allowed_domains = ["books.toscrape.com"]
    start_urls = ["https://books.toscrape.com"]

    def parse(self, response):
        books = response.css("article.product_pod")
                             
        for book in books:
            yield{
                "name":book.css("h3 a::text").get(),
                "price":book.css(".product_price .price_color::text").get(),
                "url": book.css("h3 a").attrib["href"],
            }
