接触了Ruby,发现它有个包管理工具RubyGem很好用,并且有很完备的文档系统http://rdoc.info

发现Python下也有同样的工具,包括easy_install和Pip。不过,我没有细看easy_install的方法,这就简单的介绍一下Pip的安装与使用:

1,查看linux下是否有python-pip包,

[root@localhost work]# yum install python-pip

Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base: centos.ustc.edu.cn
* extras: centos.ustc.edu.cn
* updates: ftp.twaren.net

No package python-pip available.
Error: Nothing to do

没有此rpm包,此包包含在epel源里面

[root@localhost ~]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
Retrieving http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

Preparing...                ########################################### [100%]
  1:epel-release           ########################################### [100%]


安装扩展包源完成.

接着安装python-pip

[root@localhost ~]# yum install python-pip

。。。。。。。。。。。。。。。。。。。。。。。。

Installing : python-setuptools-0.6.10-3.el6.noarch

python-pip.noarch 0:1.3.1-4.el6

Dependency Installed:
python-setuptools.noarch 0:0.6.10-3.el6

Complete!  
安装python-pip完成,在linux,shell中键入pip测试看有无该指令。

2,使用

[root@localhost ~]# pip

Usage:  
 pip [options]

 install                     Install packages.

应该这些没有问题

比如安装某个模块,redis

[root@localhost ~]# pip install redis
Downloading/unpacking redis
 Downloading redis-2.8.0.tar.gz (286kB): 286kB downloaded
 Running setup.py egg_info for package redis
Installing collected packages: redis
 Running setup.py install for redis
Successfully installed redis
Cleaning up...

安装完成。

可以在python shell中import redis测试看是否安装成功,
