python-2.7 - AttributeError: 'module' 对象没有属性 'update_settings' scrapy 1.0.5

Question

爬虫通过命令行工作正常，给出了这个错误:

2016-03-30 03:47:59 [scrapy] INFO: Scrapy 1.0.5 started (bot: scrapybot)
2016-03-30 03:47:59 [scrapy] INFO: Optional features available: ssl, http11
2016-03-30 03:47:59 [scrapy] INFO: Overridden settings: {'USER_AGENT': 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)'}

Traceback (most recent call last):
  File "/home/ahmeds/scrapProject/crawler/startcrawls.py", line 11, in <module>
    process.crawl(onioncrawl)
  File "/usr/local/lib/python2.7/dist-packages/scrapy/crawler.py", line 150, in crawl
    crawler = self._create_crawler(crawler_or_spidercls)
  File "/usr/local/lib/python2.7/dist-packages/scrapy/crawler.py", line 166, in _create_crawler
    return Crawler(spidercls, self.settings)
  File "/usr/local/lib/python2.7/dist-packages/scrapy/crawler.py", line 32, in __init__
    self.spidercls.update_settings(self.settings)
AttributeError: 'module' object has no attribute 'update_settings'

这是我按照 latest documentation 通过脚本运行我的爬虫的代码.我的scrapy版本是1.0.5。

from scrapy.crawler import CrawlerProcess
from scrapy.utils.project import get_project_settings
from crawler.spiders import onioncrawl

setting = get_project_settings()
process = CrawlerProcess(setting)
process.crawl(onioncrawl)
process.start()

我使用的是 Spider 文件名而不是 Spider 类名。
