Question

Reading article : https://medium.com/@misteryomi/integrating-laravel-passport-in-your-lumen-project-with-example-1c2b8719c30

I try to install in lumen app laravel\passport with use of dusterio/lumen-passport pluging, but I stuck on app/Models/User.php modifications :

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;
use DB;
use Illuminate\Validation\Rule;
use Laravel\Passport\HasApiTokens;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;

class User extends Model implements AuthenticatableContract, AuthorizableContract
{
    use HasApiTokens, Authenticatable, Authorizable;
    protected static $password_length = 8;

I got error message: "Trait 'App\Models\Authenticatable' not found. I tried to include with use ... different file I found in net, but failed.

In my composer.json :

{
    "name": "laravel/lumen",
    "description": "The Laravel Lumen Framework.",
    "keywords": ["framework", "laravel", "lumen"],
    "license": "MIT",

    },

            "tests/"

            "@php -r \"file_exists('.env') || copy('.env.example', '.env');\""
        ]
    }
}

How to fix it ?

Thanks!

Well, if the application can't find the passport's classes, you can force reinstall the dependencies using the composer command.

composer require dusterio/lumen-passport

or you can reinstall all the dependencies using

composer install
