php - “不能使用 Intervention\Image\Facades\Image 作为图像，因为该名称已在使用中”

问题描述

我试图弄清楚如何使用干预图像库，但我收到了这个错误。我在他们的网站上关注了 Laravel 集成，这让我做了以下事情。

安装 Intervention Image 后，打开 Laravel 配置文件 config/app.php 并添加以下行。

在$providers数组中添加此包的服务提供者。

Intervention\Image\ImageServiceProvider::class

将此包的外观添加到$aliases数组中。

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

我有一个模型Image.php，我不确定这是否重要。

'providers' => [

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

         */
        App\Providers\AppServiceProvider::class,
        App\Providers\AuthServiceProvider::class,
        // App\Providers\BroadcastServiceProvider::class,
        App\Providers\EventServiceProvider::class,

图像模型

<?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');
    }
}

解决方案

这可能是Laravel 5.5 中引入的自动发现功能导致的错误。

由于包会自动注册别名，而您是手动注册的，因此它最终会被复制。

要解决它，请从文件中删除服务提供者和别名并尝试直接使用它。您可以在执行时检查包是否自动发现 a composer dumpautoload，它将生成如下输出：

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

它应该显示intervention/image发现的包。您可以检查在他们的composer.json.

现在，为了同时使用这两个类，您需要为其中一个类分配一个新别名，例如：

use Image as InterventionImage;
use App\Image;

希望这对您有所帮助。
