Errors when running the lastgenre plugin manually

[fiso64]

I'm trying to get per-track genre tags for my entire library. I do not want any of beets' organization features. Here is the config I'm trying to use located at %APPDATA%/beets/config.yaml:

library: ~/beets/musiclibrary.db

import:
    write: no 
    copy: no
    move: no
    hardlink: no
    resume: ask
    log: beetslog.txt

plugins: musicbrainz lastgenre

lastgenre:
    force: yes
    keep_existing: no
    separator: '; '
    auto: no
    source: track
    fallback: album
    min_weight: 10
    count: 2
    canonical: yes
    whitelist: no

    extended_debug: yes

I import a test folder (which includes some very well known songs that definitely have genres on lastfm):

beet import ~\Random\BeetsTest -s

the songs import successfully. Then, I run

beet lastgenre -p

but there is no output.
The docs mention that by default beet lastgenre "matches albums". I don't really understand what it means in the context of applying genre tags to my library. They say that to match individual tracks or singletons, you have to use the -A flag. I try that as well:

beet lastgenre -A -p

but this gives me a long list of errors:

> $ beet lastgenre -A -p

No logs are produced in either case.

You don't have the musicbrainz plugin enabled. You need to enable it now manually.

Thanks. After enabling it the import command works as expected.

However, I'm still having the same issues with the lastgenre plugin.

[fiso64]

I should have run with -vv. I have opened an issue here: #6191
