pip安装python模块方法

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.douban.com 豆瓣

 

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

 

2>通过配置文件永久指定pypi镜像源地址，linux下的默认配置文件一般为 ~/.pip/pip.conf

内容配置为：

　　[global]

　　index-url = http://pypi.douban.com/simple #豆瓣源，可以换成其他的源

　　trusted-host = pypi.douban.com            #添加豆瓣源为可信主机，要不然可能报错 

　　disable-pip-version-check = true          #取消pip版本检查，排除每次都报最新的pip

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):
File "versionbuild/recreate_srpm_version_repo.py", line 22, in <module>

from paramiko.kex_curve25519 import KexCurve25519
File "/usr/lib/python2.7/site-packages/paramiko/kex_curve25519.py", line 6, in <module>
from cryptography.hazmat.primitives.asymmetric.x25519 import (
ImportError: No module named x25519

，这时可以采用更新模块方法

(pyenv2.7) [root@localhost scripts]# pip install fabric --upgrade
