【问题】
通过Scrapy创建好了项目：
root@ubuntu:~/PythonProject#scrapy startproject tutorial
运行项目，结果出错：
root@ubuntu:~/PythonProject# scrapy crawl dmoz -o items.jsonScrapy 1.1.2 - no active projectUnknown command: crawlUse "scrapy" to see available commands
【解决过程】
1.参考：
Trying to get Scrapy into a project to run Crawl command
然后才知道，原来是需要切换到对应的项目所在文件夹，再运行crawl，才可以的。
2.所以去，切换到项目所在目录songtaste子文件夹中，再运行，就可以了：

【总结】
虽然此错误，很低级，但是，由于新接触Scrapy，由于不太熟悉，所以还是很容易犯的。
