Python 2.6.6升级到Python2.7.13后离线安装各模块

（1）运行失败无IPy模块

tar zxvf IPy-0.81.tar.g
cd IPy-0.81
python setup.py install

（2）运行失败无requests模块
ImportError: No module named requests

下载地址
https://pypi.org/project/requests/
tar vxf requests-2.24.0.tar.gz
cd requests-2.24.0
python setup.py install

（3）运行失败无setuptools模块

下载地址https://pypi.org/project/setuptools/36.5.0/#files
unzip setuptools-36.5.0.zip
cd setuptools-36.5.0
python setup.py install

（4）运行失败无urllib3模块
ImportError: No module named urllib3

下载地址
https://github.com/urllib3/urllib3

unzip urllib3-master.zip
cd urllib3-master
python setup.py install

(5)又报错！！那说明setuptools安装的版本太低，可参考考https://blog.csdn.net/baidu_23491131/article/details/99671929
