Scrapy：AttributeError：'list'對象沒有屬性'iteritems'

這是我第一個關於堆棧溢出的問題。最近我想用linked-in-scraper，所以我下載並指示「scrapy crawl linkedin.com」，並得到下面的錯誤信息。爲了您的信息，我使用了anaconda 2.3.0和python 2.7.11。所有相關的軟件包，包括Scrapy和六個，在執行該程序之前都通過點更新。Scrapy：AttributeError：'list'對象沒有屬性'iteritems'

return d.iteritems(**kw) 

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

我知道這個錯誤源於d不是字典類型，而是列表類型。由於錯誤來自scrapy上的代碼，可能是scrapy包或六個包的問題。我怎樣才能解決這個錯誤？

編輯：這是代碼scrapy.cfg

# 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

您是否有Scrapy的配置文件？它看起來像是期待讀取一個詞典，但是會找到一個列表。 –

@ValentinLorentz是的我添加了上面的代碼。但我認爲它沒有關於這個問題的額外信息。編程人員構建的這段代碼說，它在Python 2.7.6上運行良好。 – user124697

這是通過鏈接在刮板的settings造成的：

ITEM_PIPELINES = ['linkedIn.pipelines.LinkedinPipeline']

然而，ITEM_PIPELINES應該是一個字典， according to the doc：

To activate an Item Pipeline component you must add its class to the ITEM_PIPELINES setting, like in the following example:
ITEM_PIPELINES = { 
    'myproject.pipelines.PricePipeline': 300, 
    'myproject.pipelines.JsonWriterPipeline': 800, 
} 
The integer values you assign to classes in this setting determine the order in which they run: items go through from lower valued to higher valued classes. It’s customary to define these numbers in the 0-1000 range.

根據this question，它曾經是一個列表，這解釋了爲什麼這個刮板使用一個列表。因此，您必須要求您的開發人員更新他們的代碼，或者自己設置ITEM_PIPELINES。

簡短的答案是ITEM_PIPELINES應該是一個字典而不是一個列表，其中鍵爲流水線類，並且值是一個整數，用於確定它們的運行順序：項從較低值到較高值類經歷。通常在0-1000範圍內定義這些數字。正如@valentin所解釋的那樣Lorentz
