我刚开始学习scrapy。所以我跟着scrapy documentation。我刚写了那个网站上提到的第一个蜘蛛。

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)

在项目的根目录上运行此scrapy crawl dmoz命令时,将显示以下错误。

您使用的是 old Scrapy(0.14.4)和最新的文档。
解决方案:升级至最新版本的Scrapy或读取old docs,这适合当前安装的版本

使用sudo pip install scrapy。如果出现Python.h missing错误,则安装带有sudo apt-get install python-devreference)的python头文件

在我的例子中,错误消息稍有不同
属性错误:部分初始化的模块'scrapy'没有属性'Spider'(很可能是因为循环汇入)
这是因为我的脚本文件名(scrapy.py)。请确保您运行的目录中没有另一个名为scrapy.py的文件,因为它将在真实的的scrapy模块之前导入。

也许可以试试:

from scrapy import Spider

如果你想使用模块的类,仅仅导入模块是不够的
