-Install Pipenv before importing requests

在WIN8下使用Python2.7 64bit。在pyhton/scripts文件下，pip.exe pip2.exe是存在的，在CMD命令行下，pip --version 无法参看版本号，这是因为没有配置环境变量的原因。将pip.exe所在的目录配置到环境变量就OK了。然后安装pipenv

pip install --user pipenv

(https://pip.pypa.io/en/stable/installing/)

(D:\Python\code\get-pip.py)

(https://docs.pipenv.org/)

-Import Requests module

Requests is an elegant and simple HTTP library for Python, built for human beings.

pip install requests
