Scrapy安装全过程（附带所有需要的软件）

原文地址，我把安装过程中需要的软件做了备份，防止以后那些网站资源挂掉。

我的网盘里放的Twisted和zope.interface分别有两个版本，之前我都用他们的最新版装完发现有错误，好像是缺少模块win32api。我又重新按照那些步骤重新装了一次，不同的是，这次我用了他们俩的低版本，装完就好了，scrapy的版本用新的没问题。

Twisted-12.1.0.win32-py2.7.msi　　

Twisted-13.0.0.win32-py2.7.msi

zope.interface-4.0.1-py2.7-win32.egg

zope.interface-4.0.5-py2.7-win32.egg

 安装过程中可能出现这样的错误：

Downloading https://pypi.python.org/packages/source/l/lxml/lxml-3.3.0beta2.tar.g

ERROR: 'xslt-config' 不是内部或外部命令，也不是可运行的程序
或批处理文件。

　　这是它想自己通过easy_install lxml的方式安装lxml，这样就会出现‘xslt-config’ 不是内部或外部命令这样的错误。手工执行easy_install lxml也会出现这样的错误，需要换一种方式安装lxml。

可以使用安装.egg 文件的方式来安装：

到http://pypi.python.org/pypi/lxml/2.3/网站上下载对应的lxml .egg 文件

然后使用下面的方式来安装：

easy_install D:\Program Files\Python2.7\lxml-2.3.py2.7.win32.egg

然后继续重新安装scrapy。

验证安装：
