ML kit demo setupandinstall command error

[semiarte]

Hi!

I´ve followed your steps to run Firebase ML Kit demo, but the command npm run install returns this:

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! nativescript-plugin-firebase@10.5.2 package: `cd ../publish && ./pack.sh`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the nativescript-plugin-firebase@10.5.2 package script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

What´s the problem?
