"Cannot use Intervention\Image\Facades\Image as Image because the name is already in use"

Question

I am trying to figure out how to use Intervention Image library but I'm getting this error. I followed the Laravel integration on their website which had me do the following.

After you have installed Intervention Image, open your Laravel config file config/app.php and add the following lines.

In the $providers array add the service providers for this package.

Intervention\Image\ImageServiceProvider::class

Add the facade of this package to the $aliases array.

'Image' => Intervention\Image\Facades\Image::class

I have a model called Image.php and I'm not sure if that matters.

'providers' => [

        /*
         * Laravel Framework Service Providers...
         */
        Illuminate\Auth\AuthServiceProvider::class,
        Illuminate\Broadcasting\BroadcastServiceProvider::class,

Image Model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Image extends Model
{
    public function user(){
        return $this->belongsTo('App\User');
    }

    public function tags(){
        return $this->belongsToMany('App\Tag','tag_image','image_id','tag_id');
    }

    public function votes(){
        return $this->hasMany('App\Vote');
    }
}

This is probably an error caused by the auto-discovery feature introduced in Laravel 5.5.

Since the package is automatically registering the alias and you are registering manually it ends up being duplicated.

To solve it remove the service provider and the alias from the file and try to use it directly. You can check if the package is auto discovered when you execute a composer dumpautoload, it will generate an output like:

Generating optimized autoload files
Illuminate\Foundation\ComposerScripts::postAutoloadDump
@php artisan package:discover
Discovered Package: fideloper/proxy 
Discovered Package: laravel/tinker
Package manifest generated successfully.

It should show the intervention/image package discovered. You can check this behaviour implemented in their composer.json.

Now in order to use both classes at the same time you would need to assign a new alias to one of them like:

use Image as InterventionImage;
use App\Image;

Hope this helps you.
