You often encounter when installing components such as oslo.config

Not uninstalling oslo.config at / usr/lib/python2.7/dist-packages, owned by OS

That kind of problem.

The reason is

/ usr/lib/python2.7/dist-packages system level, the path to python is found here first, and / usr/local/lib/python2.7/dist-packages user level cannot be used even if there is a higher version in / local when the former has a lower version of the component installed.

Preliminary solution:

Go to / usr/lib rm-rf and delete the xxxxxx-info
