Question

我最近发表了一篇关于scrapyd的工作报道。我在运行刮擦时收到以下错误消息。

我审核了这个已结束的问题：https://github.com/scrapy/scrapy/issues/86并按照文档实施了建议的修正：http://scrapyd.readthedocs.org/en/latest/config.html

我的配置文件位于：/etc/scrapyd/conf.d/000-default

我似乎无法通过将items_dir设置为none来禁用Feedexporter扩展。是否有一种新方法可以在scrapyd中禁用feedexporter？

配置文件：

[scrapyd]
http_port  = 6800
debug      = off
#max_proc  = 1
eggs_dir   = /var/lib/scrapyd/eggs
dbs_dir    = /var/lib/scrapyd/dbs
items_dir  =
logs_dir   = /var/log/scrapyd

错误讯息：

我可以通过将以下行添加到settings.py

来禁用scrapyd中的FeedExporter

EXTENSIONS = {'scrapy.contrib.feedexport.FeedExporter': None}

禁用FeedExporter解决了这个问题。

Scrapyd错误：exceptions.AttributeError：＆＃39; dict＆＃39;对象没有属性＆＃39;字段＆＃39;
