ImportError: cannot import name combinations_with_replacement

[kb1sph]

I'm running CentOS 6.8 and have installed python-setuptools and python-pip. There is no python-wheel package that I can find to install.

When I run the command, sepconf generate 2 --phone=7960 --render=asterisk.tmpl, I get the following error.

Traceback (most recent call last):

your python ver is 2.6? combinations_with_replacement is in standard lib in itertools from python 2.7.
Please upgrade your python.

P.S: for those who have python 3+ and look for some solution: make sure you did not spell it wrong when imported, for example my atom suggested WRONG name (misspelled there) and I was confused for a while. Verify that you imported name correctly, letter by letter, it might save your time :D
