今天准备在Cent OS7中运行yum install python报如下错误：
[root@bogon ~]# yum install python-dev
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.nju.edu.cn
* updates: mirrors.nju.edu.cn
File "/usr/libexec/urlgrabber-ext-down", line 28
except OSError, e:
^
SyntaxError: invalid syntax
Exiting on user cancel
Cent OS7中安装的版本是:
[root@bogon ~]# python -V
Python 3.5.2
从网上查是因为urlgrabber-ext-down这个文件没有修改
[root@bogon ~]# vi /usr/libexec/urlgrabber-ext-down
将#! /usr/bin/python 更新为#! /usr/bin/python2.7.5（我的旧版本中是2.7.5）
#! /usr/bin/python2.7.5
# A very simple external downloader

保存后正常
