When I installed toml it worked:

nautobot_blog/nautobot % pip3 install toml                                                                                                                             (tim-fiola-doc-blog)nautobot

I can update the docs to reflect this

[glennmatthews]

Good catch!

Personally, I think rather than updating the docs it would be ideal to fix tasks.py - the only task that actually requires the toml library is the docker_push task, which is intended mostly for CI usage; none of the user-facing tasks need it.

This issue appears to have been introduced by #195.
