Php Laravel 5.2级'；照亮\Html\HtmlServiceProvider'；找不到

我最近决定从laravel 5.1升级到5.2。我的composer.json文件如下所示：

{
  "name": "laravel/laravel",
  "description": "The Laravel Framework.",
  "keywords": ["framework", "laravel"],
  "license": "MIT",
  "type": "project",
  "require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "laracasts/flash": "dev-master",
    "laravelcollective/html": "5.2.0",
    "intervention/image": "^2.3",
    "cviebrock/image-validator": "^2.0"

  },
  "require-dev": {
      "fzaninotto/faker": "~1.4",
      "mockery/mockery": "0.9.*",
      "phpunit/phpunit": "~4.0",
      "phpspec/phpspec": "~2.1",
      "symfony/dom-crawler": "~3.0",
      "symfony/css-selector": "~3.0"
 },
 "autoload": {
    "classmap": [
        "database"
    ],
    "files": ["app/Http/helpers.php"],
    "psr-4": {
        "App\\": "app/"
    }
 },
 "autoload-dev": {
    "classmap": [
        "tests/TestCase.php"
    ]
 },
 "scripts": {
    "post-install-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-update-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-root-package-install": [
        "php -r \"copy('.env.example', '.env');\""
    ],
    "post-create-project-cmd": [
        "php artisan key:generate"
    ]
 },
 "config": {
    "preferred-install": "dist"
 },
 "minimum-stability": "dev",
 "prefer-stable": true
}

'providers' => [

    Illuminate\Auth\AuthServiceProvider::class,
    // some more...
    Illuminate\View\ViewServiceProvider::class,
    Collective\Html\HtmlServiceProvider::class,

    Laracasts\Flash\FlashServiceProvider::class,
    Intervention\Image\ImageServiceProvider::class,
    Cviebrock\ImageValidator\ImageValidatorServiceProvider::class,

],

'aliases' => [

    'App'       => Illuminate\Support\Facades\App::class,
    // some more...
    'Form'      => Collective\Html\FormFacade::class,
    'Html'      => Collective\Html\HtmlFacade::class,
    'Image'     => Intervention\Image\Facades\Image::class,
],

My app.php文件中的My providers数组如下所示：

{
  "name": "laravel/laravel",
  "description": "The Laravel Framework.",
  "keywords": ["framework", "laravel"],
  "license": "MIT",
  "type": "project",
  "require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.2.*",
    "laracasts/flash": "dev-master",
    "laravelcollective/html": "5.2.0",
    "intervention/image": "^2.3",
    "cviebrock/image-validator": "^2.0"

  },
  "require-dev": {
      "fzaninotto/faker": "~1.4",
      "mockery/mockery": "0.9.*",
      "phpunit/phpunit": "~4.0",
      "phpspec/phpspec": "~2.1",
      "symfony/dom-crawler": "~3.0",
      "symfony/css-selector": "~3.0"
 },
 "autoload": {
    "classmap": [
        "database"
    ],
    "files": ["app/Http/helpers.php"],
    "psr-4": {
        "App\\": "app/"
    }
 },
 "autoload-dev": {
    "classmap": [
        "tests/TestCase.php"
    ]
 },
 "scripts": {
    "post-install-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-update-cmd": [
        "php artisan clear-compiled",
        "php artisan optimize"
    ],
    "post-root-package-install": [
        "php -r \"copy('.env.example', '.env');\""
    ],
    "post-create-project-cmd": [
        "php artisan key:generate"
    ]
 },
 "config": {
    "preferred-install": "dist"
 },
 "minimum-stability": "dev",
 "prefer-stable": true
}

'providers' => [

    Illuminate\Auth\AuthServiceProvider::class,
    // some more...
    Illuminate\View\ViewServiceProvider::class,
    Collective\Html\HtmlServiceProvider::class,

    Laracasts\Flash\FlashServiceProvider::class,
    Intervention\Image\ImageServiceProvider::class,
    Cviebrock\ImageValidator\ImageValidatorServiceProvider::class,

],

'aliases' => [

    'App'       => Illuminate\Support\Facades\App::class,
    // some more...
    'Form'      => Collective\Html\FormFacade::class,
    'Html'      => Collective\Html\HtmlFacade::class,
    'Image'     => Intervention\Image\Facades\Image::class,
],

我执行

composer更新

，并得到以下错误：

> C:\ProgramData\ComposerSetup\bin\composer.bat update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
> php artisan clear-compiled


   [Symfony\Component\Debug\Exception\FatalErrorException]  
    Class 'Illuminate\Html\HtmlServiceProvider' not found    


Script php artisan clear-compiled handling the post-update-cmd event   
returned with error code 255

当我尝试运行

php artisan serve

时，我会遇到相同的错误。我尝试了所有常用的东西，比如

composer dump autoload

等等

为什么会发生这种情况？解决方法是什么？

摘自

首先将这一行添加到composer.json

"laravelcollective/html": "5.2.0"

然后执行

composer更新

等待更新完成，然后打开config/app.php添加以下内容：

Collective\Html\HtmlServiceProvider::class 

到提供程序数组，并执行以下操作：

'Form'      => Collective\Html\FormFacade::class,
'Html'      => Collective\Html\HtmlFacade::class,

到别名数组，并确保在blade中使用Html时，或在任何地方使用小写“Html”而不是Html

---

请注意，正如这个答案所说，您首先添加composer.json行，然后进行更新，然后将这些行添加到app.php。您无法将这两个步骤结合起来并使其工作。

已设法修复。我在整个项目中进行了搜索，以查看它是否仍在任何地方被引用。瞧，它仍然在macroserviceprovider中被引用，所以我将它改为使用

Collective\Html\HtmlServiceProvider取而代之
 可能重复尝试删除供应商并运行
composer安装
first@feniix已经检查了所有可能的解决方案，包括您链接到的解决方案，但该解决方案不起作用。@apokryfos尝试删除并运行
composer安装
仍会收到相同的错误。
illighted\Html\HtmlServiceProvider
显然缓存在某个地方，因为代码中不应该有任何对它的引用。尝试清除整个
存储
和
引导/缓存
目录。另外，对
illumb\Html\HtmlServiceProvider
的全局搜索也不会有任何影响。我已经尝试了所有其他类似帖子中关于此问题的所有解决方案，包括上述内容，但都不起作用。@adam78我在你的composer.json中没有看到illumb/Html。您甚至可以在laravel安装目录中的任何位置找到该类吗？确保您至少拥有它。@Chad Fisher它不存在于供应商目录中，因为它已被删除。这就是为什么我使用LaravelCollective@adam78你反对把它添加到你的项目中吗？似乎还有什么东西需要它。
