不存在scrapy设置 [英] scrapy setting is not existed

问题描述

我的蜘蛛中有这行代码

settings.overrides['JOBDIR']= self.domain+"_"+self.Category+"_"+self.Action

我收到此错误:

__
    settings.overrides['JOBDIR']= self.domain+"_"+self.Category+"_"+self.Action
NameError: global name 'settings' is not defined

我从这样的脚本运行我的蜘蛛:

I run my spider from a script like this:

def setup_crawler(domain):
    spider = GeneralSpider(xmlFile=domain)
    settings = get_project_settings()
    crawler = Crawler(settings)
    crawler.configure()
    crawler.crawl(spider)
    crawler.start()

推荐答案

get_project_settings() 查找要设置的环境变量 SCRAPY_SETTINGS_MODULE.确保它已在您的环境中设置.文档此处 解释了如何设置它.

get_project_settings() looks for the environment variable SCRAPY_SETTINGS_MODULE to be set. Make sure it is set in your environment. The documentation here explains how to set it.
