求助：scrapy建的第一只蜘蛛?报错
新人一枚，费尽千辛万苦终于在win7下把scrapy安装好，按照文档写出了第一只spider，但运行时还是报错了
我安装的OpenSSL是"egenix-pyopenssl-0.13.3.1.0.1.6.win-amd64-py2.7.msi"，在python下import无碍，scrapy也可以在cmd中正常启动和创建项目了。
下面是错误提示，求高手指教：

最开始我是用easy_install去安装 cryptography,结果出现这个问题,后来找到说用pip安装 cryptography就行了.
BTW:windows玩这个纯粹折磨自己,还是去linux下吧
谢了，这个确实是折磨，不敢玩了
请参考此文章，瞬间安装好scrapy。
