Scrapy:AttributeError:'list'对象没有属性'iteritems'

Question

这是我关于堆栈溢出的第一个问题.最近我想使用Linked-in-scraper,所以我下载并指示"scrapy crawl linkedin.com"并获得以下错误消息.为了您的信息,我使用anaconda 2.3.0和python 2.7.11.在执行程序之前,所有相关的包(包括scrapy和6)都会由pip更新.

Traceback (most recent call last):
  File "/Users/byeongsuyu/anaconda/bin/scrapy", line 11, in <module>
    sys.exit(execute())
File "/Users/byeongsuyu/anaconda/lib/python2.7/site-packages/scrapy/cmdline.py", line 108, in execute
settings = get_project_settings()

self.update(values, priority)

  File "/Users/byeongsuyu/anaconda/lib/python2.7/site-packages/six.py", line 599, in iteritems
return d.iteritems(**kw)

AttributeError: 'list' object has no attribute 'iteritems'

据我所知,这个错误源于d不是字典类型而是列表类型.而且由于错误来自scrapy上的代码,可能是scrapy包或六包上的问题.我该如何尝试修复此错误？

编辑:这是来自scrapy.cfg的代码

  # Automatically created by: scrapy start project
  #
  # For more information about the [deploy] section see:
  # http://doc.scrapy.org/topics/scrapyd.html
  [settings]  
  default = linkedIn.settings

   [deploy]
   #url = http://localhost:6800/
   project = linkedIn

Answer 1

这是由链接的刮刀设置引起的:

ITEM_PIPELINES = ['linkedIn.pipelines.LinkedinPipeline']

然而,根据文件,ITEM_PIPELINES应该是一个字典:

要激活Item Pipeline组件,必须将其类添加到ITEM_PIPELINES设置中,如下例所示:

ITEM_PIPELINES = {
    'myproject.pipelines.PricePipeline': 300,
    'myproject.pipelines.JsonWriterPipeline': 800,
}

您在此设置中为类分配的整数值决定了它们运行的​​顺序:项目从较低值到较高值类别.习惯上在0-1000范围内定义这些数字.

根据这个问题,它曾经是一个列表,它解释了为什么这个刮刀使用列表.因此,您必须要求刮刀的开发人员更新他们的代码,或者ITEM_PIPELINES自己设置.
