Usage: $0 [options]
Options:
--help display this help and exit
--confirm-root install as root without asking confirmation
--confirm-install confirm installation without asking confirmation
--confirm-pi confirm installation of PI specific nodes without asking confirmation
--skip-pi skip installing PI specific nodes without asking confirmation
--restart restart service if install succeeds
--allow-low-ports add capability to bind to ports below 1024 (default is disallow)
--update-nodes run npm update on existing installed nodes (within scope of package.json)
--no-init don't ask to initialise settings if they don't exist
--nodered-user specify the user to run as, useful for installing as sudo - e.g. --nodered-user=pi
--nodered-version if not set, the latest version is used - e.g. --nodered-version="3.0.1"
--node12 if set, forces install of major version of nodejs 12 LTS
--node14 if set, forces install of major version of nodejs 14 LTS
--node16 if set, forces install of major version of nodejs 16 LTS
--node18 if set, forces install of major version of nodejs 18 LTS
if none set, install nodejs 16 LTS if nodejs version is less than 14,
otherwise leave current install
Note: if you use allow-low-ports it may affect the node modules paths - see https://stackoverflow.com/a/65560687
