centos 7 yum命令报错

[weixin_43135728]

执行yum命令的时候报错提示：There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

/lib64/libxml2.so.2: symbol gzopen64, version ZLIB_1.2.3.3 not defined in file libz.so.1 with link time reference

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, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

If you cannot solve this problem yourself, please go to
the yum faq at:

python 换个2.6的，然后修改/usr/bin/yum 中的python路径。
