For ''systemd'' services, this should be sufficient:

    [Service]
    User=slack
    Group=slack
    WorkingDirectory=/home/slack/porridge/daemon
    # sbin shouldn't be needed if you are running as a normal user
    # Environment="PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin"
    Environment="PATH=/bin:/usr/bin:/usr/local/bin"
    # I have had "chruby-exec[157986]: zsh:1: command not found: chruby" when using zsh
    Environment="SHELL=/bin/bash"
    ExecStart=chruby-exec 3.0.3 -- /home/slack/porridge/weather/bin/weatherd
    # This worked for some services but threw gem errors for others
    # ExecStart=/opt/rubies/ruby-3.0.3/bin/ruby /home/slack/porridge/weather/bin/weatherd
