Scrapy : 0.18.2 
lxml : 3.2.3.0 
libxml2 : 2.7.8 
Twisted : 12.0.0

Может кто-нибудь помочь? Заранее спасибо!

Answer 1

Вот моя среда, и я могу без проблем запустить scraw crawl dmoz. (DMOZ исходный код можно найти здесь https://github.com/scrapy/dirbot)

$ Scrapy version -v 
Scrapy : 0.18.2 
lxml : 3.2.3.0 
libxml2 : 2.7.8 
Twisted : 13.1.0 
Python : 2.7.2 (default, Oct 11 2012, 20:14:37) - [GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] 
Platform: Darwin-12.4.0-x86_64-i386-64bit 

Может быть, вы можете использовать пип обновления как этот

pip install --upgrade Scrapy
