Scrapy 1.1.2 在 python3.4.4 安装成功。
并用了 Scrapy bench 作测试：

从反馈的信息上看，是成功的。
然后，我按照这个帖子做例子：scrapy简单学习
却提示出错了，如下：

C:\Documents and Settings\Administrator>scrapy crawl dmoz -o items.json Scrapy 1.1.2 - no active project Unknown command: crawl Use "scrapy" to see available commands

有哪位知道具体怎么运用Scrapy 1.1.2 吗?
