There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
/root/anaconda3/lib/liblzma.so.5: version `XZ_5.1.2alpha' not found (required by /lib64/librpmio.so.3)
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, Aug 4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]
If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
解决办法:

vim .bash_profile export LD_LIBRARY_PATH=/lib64/:$LD_LIBRARY_PATH source .bash_profile
