我在64位操作系统上运行32位python 2.7.3版本。（我尝试了64位，但没有锻炼）。

我按照教程进行操作，并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时显示错误。当我在（C：\ python27 \ scripts）下点击scrapy命令时，我发现了这件事：

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)
  settings      Get settings values
  shell         Interactive scraping console
  startproject  Create new project
  version       Print Scrapy version
  view          Open URL in browser, as seen by Scrapy

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，任何人都可以帮忙..在此先感谢..
