Installing on MacOS (M5)

Hi, I'm getting this error when I try to push:

ERROR:  While executing gem ... (Gem::UnknownCommandError)
    Unknown command neocities
	/opt/homebrew/lib/ruby/site_ruby/4.0.0/rubygems/command_manager.rb:206:in 'Gem::CommandManager#find_command'

	/opt/homebrew/opt/ruby/bin/gem:12:in '<main>'

I've installed it via brew, on its own (in which case it fails, so installed --user-install), and I'm just having no luck. I added the suggested path for the brew install of Ruby to my zshrc, so it should be working - not sure where the failure is here (and it could be on the Ruby level I suppose, I don't use it outside of this, which normally works well on my kubuntu install). Any ideas what to do from here?

Sorry for the trouble.
