系统报错系列——linux下yum不可用

报错

  File "/bin/yum", line 30     except KeyboardInterrupt, e:                             ^ SyntaxError: invalid syntax

解决：linux下安装python2.7并建立软链接

1、下载python

wget https://www.python.org/ftp/python/2.7.16/Python-2.7.16.tgz

2、解压、编译安装（依次执行以下5条命令）#

tar -zxvf Python-2.7.16.tgz

cd Python-2.7.16

./configure --prefix=/usr/local/python-2.7.16

make

make install
