yum 安装报错 File “/usr/bin/yum“, line 30 except KeyboardInterrupt

在使用centos7将python从2.7升级到3.x时报的错，只需修改 /usr/bin/yum 和 /usr/libexec/urlgrabber-ext-down 文件，指定使用 python2.7 作为 yum 的解释器。

终端输入以下命令，按i修改文件，按esc退出修改，再输入:wq!保存并退出。

vim /usr/bin/yum

#!/usr/bin/python2.7
import sys
try:
    import yum
except ImportError:
    print >> sys.stderr, """\

vim /usr/libexec/urlgrabber-ext-down
