[Copy link]
Posted on 2/13/2017 3:30:11 PM | | | |
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:
2.7.5 (default, Dec  7 2016, 02:54:15)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq
Error causes:
Error reason: The error message describes that the python that yum depends on does not match, please install the corresponding python.

First, run:


The results showed:

Sure enough, there are two versions of python installed

Run python to see the version using 2.7.5





Guess yum calls a high version of python

Find the yum file, and edit this py file

Outcome:





will


Changed to:



Then save OK.
