网上搜索了很多，主流的配置方法分为两种：
摘自 1、http://www.jb51.net/article/83617.htm
安装pip的包并确定pip安装时的镜像源地址，国内常用的地址有：
http://pypi.hustunique.com 华中理工大学http://pypi.sdutlinux.org 山东理工大学http://pypi.mirrors.ustc.edu.cn 中国科学技术大学1> 临时指定pypi镜像源地址：
pip install --index-url=http://pypi.jb51.net/simple/ flask但是对我Fedora21的系统来说，如安装flask模块的话：
pip3 install flask --find-links=http://mirrors.xxx.com.cn/pypi/simple/
批量安装方法, 假如python需要的模块全部填写在requirement.txt中
PyMongo>=2.7 whoosh redis python-dateutil flask flask-login<=0.2.11 flask-pymongo tornado passlib xlrd lxml six>=1.9.0 pytz irc sleekxmpp Werkzeug Jinja2 itsdangerous click
pip3.4 install -r requirements.txt --index-url=http://mirrors.zte.com.cn/pypi/simple/
---------------------------------------------------------------------------------
备注：
如果使用pip安装完成后发现模块依赖的版本不满足但安装成功，代码执行时报相关模块不存在问题
(pyenv2.7) [root@localhost scripts]# python versionbuild/xxx_srpm_version_repo.py -v 5.04
Traceback (most recent call last):

from cryptography.hazmat.primitives.asymmetric.x25519 import (

，这时可以采用更新模块方法
