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
|
1
|
[root@ansheng ~]# yum install python-pip
|
安装完成之后可以使用pip -V查看安装版本
|

|
[root@ansheng ~]# 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

[root@ansheng ~]# 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
|
1
|
[root@ansheng ~]# 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

安装成功。
卸载执行pip uninstall加模块名
[root@ansheng ~]# pip uninstall requests
源码包方式安装
下载模块requests的源码包
