AttributeError：'模塊'對象沒有屬性'Spider'

我剛開始學習scrapy。所以我跟着scrapy documentation。我剛剛寫了該網站中提到的第一隻蜘蛛。AttributeError：'模塊'對象沒有屬性'Spider'

import scrapy 

class DmozSpider(scrapy.Spider): 
    name = "dmoz" 
    allowed_domains = ["dmoz.org"] 
    start_urls = [ 
     "http://www.dmoz.org/Computers/Programming/Languages/Python/Books/", 
     "http://www.dmoz.org/Computers/Programming/Languages/Python/Resources/" 
    ] 

    def parse(self, response): 
     filename = response.url.split("/")[-2] 
     with open(filename, 'wb') as f: 
      f.write(response.body)

在項目根目錄下運行此scrapy crawl dmoz命令時，它顯示以下錯誤。

安裝蟒蛇頭文件有一個已知的問題與使用安裝scrapy易於得到在Debian：http://stackoverflow.com/a/28736998/191442 –

最

from scrapy import Spider

只導入模塊是不夠的最新的文檔。

解決方案：升級到Scrapy的最新版本，或者閱讀old docs，那件衣服當前安裝的版本

如何找到scrapy版本？ –

@AvinashRaj在運行'scrapy'時通常會輸出。你的問題已經包含'2015-06-07 21:53:06 + 0530 [scrapy]信息：Scrapy 0.14.4開始（bot：教程）';-) – Alik

等待，一旦我更新就回復你.. –

-2

也許嘗試：如果你想使用它的您正在使用舊 Scrapy（0.14.4）班

' ImportError：無法導入名稱Spider' –

檢查'從scrapy導入*'？（儘管它不是pythonic） – kedam6

如果'scrapy.Spider'是一個模塊，並且不在'scrapy'軟件包中導入，你只會產生差異。 –

使用sudo pip install scrapy。如果你得到Python.h missing錯誤，然後用sudo apt-get install python-dev（reference）
