Python 2.7 刮刀刮不动

我可以用漂亮的汤和机械化的工具来运行python，但由于某些原因，当我尝试使用喷雾刮刀时，它就是不起作用。下面是一个示例，演示了当我尝试使用教程测试刮板时发生的情况：

项目名称&BOT名称=教程

以下脚本是我使用的items.py和settings.py

items.py

设置.py

问题是您正在将spider放入items.py

相反，创建一个包spider，在其中创建一个dmoz.py并将您的spider放入其中

请参阅本教程第段中的更多内容

import scrapy

class DmozSpider(scrapy.Spider):
    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]
        with open(filename, 'wb') as f:
            f.write(response.body)

BOT_NAME = 'tutorial'

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

C:\Users\Turbo>scrapy startproject tutorial
New Scrapy project 'tutorial' created in:
    C:\Users\Turbo\tutorial

You can start your first spider with:
    cd tutorial
    scrapy genspider example example.com

C:\Users\Turbo>cd tutorial

C:\Users\Turbo\tutorial>scrapy crawl dmoz
