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：

分不清堆栈错误提示比较明显，缺失cryptography模块 解决方法:pip install cryptography 如果你是pycharm可以setting——>Project:XXXXX——>project Interpreter中右上角点击+号输入cryptography添加
