我是python的新手.我在64位操作系统上运行python 2.7.3版本32位.(我试过64位,但没有锻炼).
我按照教程在我的机器上安装了scrapy.我创建了一个项目demoz.但是当我输入scrapy crawl demoz它时显示错误.当我点击(C:\ python27\scripts)下的scrapy命令时,我遇到了这个东西,它显示:
C:\Python27\Scripts>scrapy
Scrapy 0.14.2 - no active project
Usage:
scrapy <command> [options] [args]
Available commands:
fetch Fetch a URL using the Scrapy downloader
runspider Run a self-contained spider (without creating a project)

shell Interactive scraping console
startproject Create new project
version Print Scrapy version

Use "scrapy <command> -h" to see more info about a command
C:\Python27\Scripts>
我想他们是安装中缺少的东西,任何人都可以帮助请...提前感谢..
