Laravel 5.2:找不到类'Intervention\Image\ImageServiceProvider‘

Question

我正在尝试将干预图像集成到我的项目中。我遵循了指南，使用了一堆其他的教程，无论我做什么，我都会得到相同的错误：

Class 'Intervention\Image\ImageServiceProvider' not found

它包含在我的composer.json中

{
    "require": {
        "laravel/envoy": "~1.0",
        "laravel/installer": "^1.3",
        "intervention/image": "^2.3"
    }
}

我已经安装了php-gd的东西，包括

Intervention\Image\ImageServiceProvider::class

和

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

在我的config\app.php中，但是我一直收到令人讨厌的错误信息。也许值得一提的是，我使用的是Linux Mint OS，并且我使用的是Homestead虚拟机。是的，我在Homestead版本的Composer中包含了这些东西，而不是在我的主PC的composer中。在使用时

PHP artisan --version

，它返回：

Laravel Framework version 5.2.43

我在虚拟机上运行了composer更新，没有解决问题。我尝试从app.php中删除行，运行composer update，再次添加行，然后运行composer update，都不起作用。

在config\app.php中将inclusions放在什么位置很重要吗？现在，别名在列表中，提供程序在Package Service Providers下。

以下是完整的错误消息：

Whoops, looks like something went wrong.

Answer 1

我也遇到了同样的问题，原来我没有在我的项目根目录下运行这个命令$ php composer.phar require intervention/image。我在我的项目的根上运行了它，一切都很好。

例如Itses-MacBook-Pro:testproject bigtank$ composer require intervention/image

像这样运行它，它就会工作。

干杯。

Answer 2

从config/app.php中删除facade和服务提供者，然后运行composer dumpauto (如果不起作用，运行composer dumpauto -o)。之后，将外观和服务提供者添加回config/app.php。

Answer 3

请确保您仔细遵循了安装指南。

你需要先运行：

composer require intervention/image

而且您应该在已经安装了这个包之后(因此在运行composer require之后)而不是在安装之前修改config.app.php。
