centos7 yum安装python3无法使用yum解决办法
昨天帮朋友在阿里云上安装python3,原本以为很简单的事情,居然让我搞了半天.
系统:centos 7(64位)
软件环境:python3
1.安装yum源
yum -y install epel-release
2.安装python3
yum -y install python34 python34-pip
替换python2.7
rm -f /usr/bin/python
ln -sf /usr/bin/python3 /usr/bin/python
3.修改yum
vim /usr/bin/yum
将顶部的
#!/usr/bin/python
修改为:
#!/usr/bin/python2.7
原本以为改了这里就可以了,没想到再执行yum居然报下面的错误:
[root@rocdk890 ~]#yum -y install iftop

网上搜了下,修改/usr/libexec/urlgrabber-ext-down里的#! /usr/bin/python为#! /usr/bin/python2.7就可以解决.
