scrapy安装指南

windows 7/8 安装scrapy

#官方文档有些问题，下述安装教程通过实践   旧版安装教程

windows全部安装包下载：

           https://github.com/addwork/scrapy-windows

1.安装python2.7，将 C:\python27和C:\python27\Scripts添加至环境变量

详细参考：python与工具pip安装使用    熟悉python可以安装pip，不熟悉安装配置好python后继续。

2.安装OpenSSL，将openssl路径添(如 D:\openssl-win32\bin)添加至环境变量

依赖VC++ 的编译工具，如果安装了vc++/vs2008/vs2010/vs2012的可以直接安装OpenSSL，否则需要安装VC++目录下的执行文件，VC++2012是针对win8，win7的2012/2008均可.安装完成可执行文件即可安装OpenSSL.

3.安装包内可执行文件

pywin32，Twisted，zope.interfase，libxml，libxml2，pyOpenSSL

4. 其他压缩文件安装

解压w3lib-1.5.tar.gz,libxml-2.9.1.tar.gz,scrapy-0.22.tar.gz至D：盘

D:>cd w3lib-1.5
D:\w3lib-1.5>python setup.py install
D:\w3lib-1.5>cd d/libxslt
D:\libxslt>python setup.py install
D:\libxslt>cd d/scrapy-0.22 
D:\scrapy-0.22>python setup.py install 
D:\scrapy-0.22>python
>>>import w3lib

D:>scrapy -h
Scrapy 0.22.2 - no active project
