centos yum报错 File "/usr/bin/yum", line 30 except KeyboardInterrupt, e:
报错:
报错一:
File "/usr/bin/yum", line 30
except KeyboardInterrupt, e:
报错二:
File "/usr/libexec/urlgrabber-ext-down", line 28
except OSError, e:
原因:
以上两个报错,是因为我安装python3之后,同时让它作为默认版本软链接到/usr/bin/python
导致。
yum默认使用系统自带的python2.7作为解释器,现在默认python3.6,也就解析2.7语法报错了。
解决方法:
报错一:
编辑/usr/bin/yum
,将第一行原本/usr/bin/python
修改为/usr/bin/python2
即可,如下所示:
#!/usr/bin/python2
import sys
try:
import yum
except ImportError:

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

报错二:
编辑/usr/libexec/urlgrabber-ext-down
,也是把第一行修改为/usr/bin/python2
即可,如下所示:
#! /usr/bin/python2
# A very simple external downloader

import time, os, errno, sys
from urlgrabber.grabber import
_readlines, URLGrabberOptions, _loads,
PyCurlFileObject, URLGrabError
...(以下省略)
修正之后就可以正常使用yum了!
