Beets: ValueError when using application

[chayward1]

Problem

When using the program a ValueError is returned and the program does not function

Running this command in verbose (-vv) mode:

~ ❯❯❯ beet -vv

Can you be more specific? That issue just links to two other issues none of which I can find a fix within?

[wisp3rwind]

Those two issues would have told you that this is a known problem which is fixed in a development version but is not released yet due to limited free time of the maintainers. You could also have found a link that explains how to install the latest source as a workaround:

see the "How do I run the latest source version of beets?" section of the FAQ — that should hopefully get you started.

Didn't see those but I appreciate your help, thank you.
