python - Scrapyd错误:exceptions.AttributeError:'dict'对象没有属性'fields'

我最近发布了一份要刮的工作稿。我在运行抓取工具时收到以下错误消息。

我查看了以下已解决的问题：https://github.com/scrapy/scrapy/issues/86并根据文档进行了建议的修复：http://scrapyd.readthedocs.org/en/latest/config.html

我的配置文件位于此处：：/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。有没有一种新的方法可以在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

错误信息：

exceptions.AttributeError: 'dict' object has no attribute 'fields'

最佳答案

通过在settings.py中添加以下行，我可以在scrapyd中禁用FeedExporter

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

禁用FeedExporter可以解决此问题。
