查看python的版本
- #python -V
- Python 2.6.6
#python -V Python 2.6.6
1.下载Python-2.7.3
- #wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
#wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
2.解压
- #tar -jxvf Python-2.7.3.tar.bz2
#tar -jxvf Python-2.7.3.tar.bz2
3.更改工作目录
- #cd Python-2.7.3
#cd Python-2.7.3
4.安装
- #./configure
- #make all
- #make install
- #make clean
- #make distclean
#./configure #make all #make install #make clean #make distclean
5.查看版本信息
- #/usr/local/bin/python2.7 -V
#/usr/local/bin/python2.7 -V
6.建立软连接,使系统默认的 python指向 python2.7
- #mv /usr/bin/python /usr/bin/python2.6.6
- #ln -s /usr/local/bin/python2.7 /usr/bin/python
#mv /usr/bin/python /usr/bin/python2.6.6 #ln -s /usr/local/bin/python2.7 /usr/bin/python
7.重新检验Python 版本
- #python -V
#python -V
8解决系统 Python 软链接指向 Python2.7 版本后,因为yum是不兼容 Python 2.7的,所以yum不能正常工作,我们需要指定 yum 的Python版本
- #vi /usr/bin/yum
#vi /usr/bin/yum
将文件头部的
#!/usr/bin/python
改成
#!/usr/bin/python2.6.6
pip 修改源
vi ~/.pip/pip.conf
