如何安装Python第三方模块
Python官方为我们提供了第三方库，那么如何安装这些库呢？
安装第三方库有两种方式：
- 第一种就是使用python自带的仓库pip进安装
- 第二种就是使用源码进行安装
PIP方式安装
首先用yum安装python-pip软件包
[[email protected] ~]# yum install python-pip
安装完成之后可以使用pip -V查看安装版本
[[email protected] ~]# pip -V pip 7.1.0 from /usr/lib/python2.6/site-packages (python 2.6)
这次就以requests模块为例把，先查看当前系统有没有安装requests模块
[[email protected] ~]# python Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56) [GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2 Type "help", "copyright", "credits" or "license" for more information. # 如果没有安装在导入的时候就会报错 >>> import requests Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named requests >>> exit()
用pip的方式安装requests模块
[[email protected] ~]# pip install requests
安装完成之后进入python解释器导入requests模块，看看能不能导入成功
[[email protected] ~]# python Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56) [GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import requests
安装成功。
卸载执行pip uninstall加模块名
[[email protected] ~]# pip uninstall requests
源码包方式安装
下载模块requests的源码包
[[email protected] ~]# git clone git://github.com/kennethreitz/requests.git Initialized empty Git repository in /root/requests/.git/ remote: Counting objects: 17546, done. remote: Compressing objects: 100% (2/2), done. remote: Total 17546 (delta 0), reused 0 (delta 0), pack-reused 17544 Receiving objects: 100% (17546/17546), 5.04 MiB | 46 KiB/s, done. Resolving deltas: 100% (11232/11232), done.
查看下载下来的文件
[[email protected] ~]# cd requests/ [[email protected] requests]# ls AUTHORS.rst docs HISTORY.rst Makefile NOTICE requests requirements.txt tests CONTRIBUTING.md ext LICENSE MANIFEST.in README.rst requirements-to-freeze.txt setup.py
执行python setup.py install进行编译安装
[[email protected] requests]# python setup.py install
验证是否安装成功
[[email protected] requests]# python Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56) [GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import requests
安装成功，以上就是Python第三方模块的两种安装方式，愿能够为你提供帮助。
