使用Python的"Scrapy"时出错

Question

我在Python 2.7上安装了最新版本的Scrapy(是的,我仍然使用这个版本),并且在运行Scrapy的教程脚本时遇到错误.我正在运行的代码是:

from scrapy.spider import BaseSpider

class DmozSpider(BaseSpider):
    name = "dmoz.org"
    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]
        open(filename, 'wb').write(response.body)

错误是:

Traceback (most recent call last):
  File "C:/Users/Rainey/Desktop/dmoz/spiders/dmoz_spider.py", line 1, in <module>
    from scrapy.spider import BaseSpider
  File "C:\Python27\lib\site-packages\scrapy\spider.py", line 7, in <module>
    from scrapy import log
  File "C:\Python27\lib\site-packages\scrapy\log.py", line 10, in <module>
    from twisted.python import log
ImportError: No module named twisted.python

教程脚本在我的桌面上.这会产生影响吗？我应该把它放在不同的地方吗？

Answer 1

错误消息" ImportError:No module called twisted.python "表示您缺少扭曲的模块.

使用像pip这样的包管理器安装或者下载Windows二进制文件.
