学习python并尝试实现scrapy

Question

我正在复习那篇无聊的教程http://doc.scrapy.org/en/latest/intro/tutorial.html 我一直跟着它直到我执行这个命令

scrapy crawl dmoz

它给了我一个错误的输出

^{pr2}$

我对python不是很熟悉，也不知道它在抱怨什么

这是我的domz_蜘蛛网.py文件

from scrapy.spider import BaseSpider

class DmozSpider(BaseSpider):
    name = "dmoz"
    allowed_domains = ["dmoz.org"]
    start_urls = [
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/",
        "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/"
    ]

    def parse(self, response):
        filename = response.url.split("/")[-2]
        open(filename, 'wb').write(response.body)

And here is my items file

# Define here the models for your scraped items
#
# See documentation in:
# http://doc.scrapy.org/en/latest/topics/items.html

from scrapy.item import Item, Field

    class DmozItem(Item):
        title = Field()
        link = Field()
        desc = Field()

这是目录结构

scrapy.cfg
tutorial/
tutorial/items.py
tutorial/pipelines.py
tutorial/settings.py
tutorial/spiders/
tutorial/spiders/domz_spider.py

这是设置.py文件

    BOT_NAME = 'tutorial'

    SPIDER_MODULES = ['tutorial.spiders']
    NEWSPIDER_MODULE = 'tutorial.spiders'

好吧，我发现这个解决了这个问题

sudo pip安装升级zope.接口在

我不知道一旦发出这个命令，发生了什么，但这解决了我的问题，现在我看到了这一点
