在spiders文件同级建立一个commands文件夹，建立一个py文件，我自定义为crawlall.py。

 

 

from scrapy.commands import ScrapyCommand
 
 
class Command(ScrapyCommand):
    requires_project = True
 
    def syntax(self):
        return '[options]'
 
    def short_desc(self):
        return 'Runs all of the spiders'
 
    def run(self, args, opts):
        spider_list = self.crawler_process.spiders.list()
        for name in spider_list:
            self.crawler_process.crawl(name, **opts.__dict__)
        self.crawler_process.start()

在settings文件里把刚建立的crawlall文件的路径设置好

COMMANDS_MODULE = "ProxyPool.commands"

最后在cmd下 scrapy crawlall 运行
