python - pycharm scrapy配置

Question

我是 scrapy 的新手，尝试使用 scrapy 配置 pycharm 。调试程序时出现错误。然后，我也尝试将我的Scrapy项目作为模型添加到PyCharm中，如下所示:

文件->设置->项目结构->添加内容根目录。它不起作用

import scrapy
from scrapy.spiders import SitemapSpider
from scrapy.spiders import Spider

       print response.url

    def _parse_sitemap(self, response):

        else:

                return

            s = Sitemap(body)
            sites = []

            print self.sitemap_urls

    # Also consider alternate URLs (xhtml:link rel="alternate")
        if alt and 'alternate' in d:

错误:

配置: 蜘蛛文件位置:

Answer 1

配置> scipts参数> 爬行[蜘蛛名称]

在您的情况下，将[spider name]替换为test:爬行测试。

更新

如果您不在 scrapy 项目中并且只是尝试运行单个文件，您可以使用 runspider [/file/path] 运行您的蜘蛛

在您的情况下:runspider items.py
