yum指令出错
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.7.12 (default, Aug 17 2017, 17:30:24)
[GCC 4.4.7 20150623 (Red Hat 4.8.5-39)]
If you cannot solve this problem yourself, please go to
