plugin command - unknown extension error

Environment

Python Version: 3.6.5

Nikola Version: 8.0.0b2

Operating System: macOS High Sierra 10.13.5/Darwin Kernel Version 17.6.0

Description:

I am trying to migrate to Nikola v8 as described in Upgrading to Nikola v8. I have updated the nikola package, and it builds without errors.

I next wanted to update the metadata, but the nikola plugin command gave me an error:

$ nikola plugin -i upgrade_metadata_v8
Scanning posts.COMPILERS in conf.py does not tell me how to handle '.html' extensions.

I checked in conf.py, and with a print, I can verify that COMPILERS is set to handle .html. But I get the same error as above.

Not every command results in this error, though. For instance, nikola status works fine. And it's not restricted to installing plugins. nikola plugin --url gives the error too.

Digging into the plugin modules, I wonder if the fact that most command plugins have needs_config = True set, but plugin command plugins have needs_config = False.

Here is my config file:

# -*- coding: utf-8 -*-

from __future__ import unicode_literals
import time

# !! This is the configuration of Nikola. !! #
# !!  You should edit it to your liking.  !! #

# ! Some settings can be different in different languages.
# ! A comment stating (translatable) is used to denote those.
# ! There are two ways to specify a translatable setting:
# ! (a) BLOG_TITLE = "My Blog"
# ! (b) BLOG_TITLE = {"en": "My Blog", "es": "Mi Blog"}
# ! Option (a) is used when you don't want that setting translated.
# ! Option (b) is used for settings that are different in different languages.

# If you want to use Nikola with a non-supported language you have to provide
# a module containing the necessary translations
# (cf. the modules at nikola/data/themes/base/messages/).
# If a specific post is not translated to a language, then the version
# in the default language will be shown instead.

# What is the default language?
DEFAULT_LANG = "en"

# What other languages do you have?
# The format is {"translationcode" : "path/to/translation" }
# the path will be used as a prefix for the generated pages location
TRANSLATIONS = {
    DEFAULT_LANG: "",
    # Example for another language:
    # "es": "./es",
}

# What will translated input files be named like?

# If you have a page something.rst, then something.pl.rst will be considered
# its Polish translation.
#     (in the above example: path == "something", ext == "rst", lang == "pl")
# this pattern is also used for metadata:
#     something.meta -> something.pl.meta

TRANSLATIONS_PATTERN = "{path}.{lang}.{ext}"

# Links for the sidebar / navigation bar.  (translatable)
# This is a dict.  The keys are languages, and values are tuples.
#
# For regular links:

#
# For submenus:
#     (
#         (

#         'Fruits'
#     )
#
# WARNING: Support for submenus is theme-dependent.
#          Only one level of submenus is supported.
# WARNING: Some themes, including the default Bootstrap 3 theme,
#          may present issues if the menu is too large.
#          (in bootstrap3, the navbar can grow too large and cover contents.)
# WARNING: If you link to directories, make sure to follow
#          ``STRIP_INDEXES``.  If it’s set to ``True``, end your links
#          with a ``/``, otherwise end them with ``/index.html`` — or
#          else they won’t be highlighted when active.
