Today, I face the same issue, whatever I retry many times, it still appears the following words:
Running @quasar/cli v1.0.0-rc.2
$ quasar <command> <options>
Help for a command
$ quasar <command> --help
$ quasar <command> -h
–version, -v Print Quasar CLI version
create Create a project folder
info Display info about your machine
(and your App if in a project folder)
upgrade Check (and optionally) upgrade Quasar packages
from a Quasar project folder
serve Create an ad-hoc server on App’s distributables
help Displays this message
=> IMPORTANT !
=> Trigger this inside of a Quasar project (and npm/yarn install) for more commands.
My operation system is MacOS and I don’t know why still now!
