`kubernaut set-token` fails with a traceback

[exarkun]

I pip install kubernaut'ed (on Python 2.7; Ubuntu). When I got to the set-token step:

Traceback (most recent call last):

I get the same error. Installed with Python 3.6.4, pip 9.0.1

@alexgervais kubernaut --version? This should be fixed in 0.1.40...

[alexgervais]

It is failing on a fresh install of kubernaut v0.1.40

[plombardi89]

I was unable to reproduce this last night, but I was able to reproduce it this morning with python 3.6.3... digging into it now.

@alexgervais I need to fix GH-31 now to get this one out officially but you can install from source with pip install -e . or pointing at the git repo.

@plombardi89 success! Thanks!
