Manjaro locale.Error: unsupported locale setting

First time install of Mycroft. I’m using Manjaro linux and I’ve seen the mycroft package in AUR but it doesn’t work so I’ve used the git readme. When I try running: /start-mycroft.sh debug`

I get an error:

    Starting cli
Traceback (most recent call last):

    "__main__", mod_spec)

  File "/usr/lib/python3.7/locale.py", line 604, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

Is there anything I need to be doing? I’ve tried looking around online but nothing seems to point me to the right direction
