yum安装的时候报错，关于python的函数库

我在执行yum -y install nc命令的时候出现如下报错

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

cannot import name partial

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:
2.7.5 (default, May  3 2017, 07:55:04)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-14)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

ansible远程执行 ansible -i ./hosts all -m ping 的时候也有个报错

}

以上报错是同一台服务器，判断为python的函数库出问题

解决方案

#cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.4 (Maipo)

#python -V
Python 2.7.5

将问题主机的/lib64/python2.7目录备份，找一台没问题的服务器，同目录下的所有文件拷贝过来，就解决问题了
