python更新

1.官网下载安装包，编译安装

./configure --prefix=/usr/local/python make && make install  2.修改旧的python2.7命令 mv /usr/bin/python /usr/bin/python2.7.5  链接python3.4的命令 ln -s /usr/local/python/bin/python3.4 /usr/bin/python 3.yum 指向旧的python命令 vim /usr/bin/yum   -->   #!/usr/bin/python2.7.5 4.验证python -V   正常显示3.4.5

yum install报错

 vim /usr/libexec/urlgrabber-ext-down  修改第一行  #!/usr/bin/python2.7.5

vim /usr/bin/gnome-tweak-tool   修改第一行  #!/usr/bin/python2.7.5

然后yum安装正常了！
