Crawlera не работает с Scrapy, загрузчик не работает

Question

Пробовал реализовать Common Practices в scrapy. Поэтому попытался внедрить библиотеку crawlera.

Установлен и настроен Crawlera как указано here. (Я могу увидеть scrapylib библиотеку в моей системе, делая help('modules'))

Это мой settings.py для Scrapy:

BOT_NAME = 'cnn' 

SPIDER_MODULES = ['cnn.spiders'] 
NEWSPIDER_MODULE = 'cnn.spiders' 
COOKIES_ENABLED = False 
DOWNLOADER_MIDDLEWARES = {'scrapylib.crawlera.CrawleraMiddleware': 600,'scrapy.contrib.downloadermiddleware.useragent.UserAgentMiddleware': None,} 
CRAWLERA_ENABLED = True 
CRAWLERA_USER = 'abc' 
CRAWLERA_PASS = 'abc@abc' 

Но когда я бегу паук ничего не происходит.

я могу видеть в моем журнале Scrapy, что CrawleraMiddleware загружен:

2013-12-23 20:12:54+0530 [scrapy] DEBUG: Enabled downloader middlewares: HttpAuthMiddleware, DownloadTimeoutMiddleware, RetryMiddleware, DefaultHeadersMiddleware, MetaRefreshMiddleware, HttpCompressionMiddleware, RedirectMiddleware, CrawleraMiddleware, ChunkedTransferMiddleware, DownloaderStats 

почему он не ползает?

Это журнал с Crawlera Enabled:

Answer 1

код 407 ошибки от Crawlera ошибка аутентификации, есть возможно опечатка в APIKEY или, возможно, вы не используете правильный.
