安装Scrapy

采用官方网站提供的安装方式，首先要保证系统已安装pip。

Installing Scrapy

You can install Scrapy using easy_install or pip (which is the canonical way to distribute and install Python packages).

Note

Check  first.

To install using pip:

pip install Scrapy

To install using easy_install:

easy_install Scrapy

我采用的是pip方式，安装过程出现问题：
