ScrapyPreactionWaring：命令'；的默认“爬虫程序”已弃用，将被删除。使用“create_crawler”方法实例化爬虫

刮擦版0.19

我正在使用此页（）上的代码。当我运行

scrapy allcrawl

时，我得到了

ScrapyDeprecationWaring: Command's default `crawler` is deprecated and will be removed. Use `create_crawler` method to instantiate crawlers

代码如下：

from scrapy.command import ScrapyCommand
import urllib
import urllib2
from scrapy import log

class AllCrawlCommand(ScrapyCommand):

    requires_project = True
    default_settings = {'LOG_ENABLED': False}

    def short_desc(self):
        return "Schedule a run for all available spiders"

    def run(self, args, opts):
        url = 'http://localhost:6800/schedule.json'
        for s in self.crawler.spiders.list(): #this line raise the warning
            values = {'project' : 'YOUR_PROJECT_NAME', 'spider' : s}
            data = urllib.urlencode(values)
            req = urllib2.Request(url, data)
            response = urllib2.urlopen(req)
            log.msg(response)

如何修复弃用警告

谢谢

使用：

crawler = self.crawler_process.create_crawler()

---

它抛出AttributeError:“CrawlerProcess”对象在scrapy 1.0.3中没有属性“create\u crawler”。如何修复此问题？@Ashish蜘蛛加载器它在

self.crawler\u process.spider\u loader

上公开，因此您可以直接在该对象上调用

.list（）

。
