晚上在家学习视频教程，运行Scrapy shell时，老是有上面的错误，然后结尾处给出错误：
twisted.internet.error.DNSLookupError: DNS lookup failed: address 'xn--http:-hw3b' not found: [Errno 8] nodename nor servname provided, or not known.

因为下午在单位用win7运行都正常，所以这个是不是和网络有关系。这个“address 'xn--http:-hw3b'”是何方妖孽？是否是我电脑设置上的问题，请大家给点提示，帮忙看下。

求帮忙～～

解决了，是我自己输入错误。
错误输入：
scrapy shell “http://www.dmoz.org/Computers/Programming/Languages/Python/Books/”

正确输入：
scrapy shell http:[url]www.dmoz.org/Computers/Programming/Languages/Python/Books/[/url]

没有双引号。之前在windos使用的时没有注意。网上查到的scrapy shell使用里面都没有带双引号。
