Script php artisan asset:publish vendor/package handling the post-update-cmd event returned with error code 1

Installation failed, reverting ./composer.json to its original content.

I am using laravel5.3 and tried composer require laravel/passport

@summermick Seems to me the problem is this command here "php artisan asset:publish vendor/package" there is no artisan command like that unless of course this was manually created. If you check your composer.json under scripts removing that command and trying again should help.

I think you mean vendor:publish:

php artisan vendor:publish --tag=passport-components

There's no asset:publish command in laravel.

I'm having this same issue with fresh Laravel 5.4 install. PHP 7. DigitalOcean server Ubuntu 16.04. Even reset the vendor items, cleared all laravel caches and composer cache.

php artisan passport:install

@newelement Did you forget to add the service provider to app.php
