Laravel 错误：在 CMD 中运行 composer require laravelcollective/html 后未找到类“Collective\Html\HtmlServiceProvider”

Laravel ERROR: Class 'Collective\Html\HtmlServiceProvider' not found after running composer require laravelcollective/html in CMD

提问by ITWitch

NOTE:No answer from this threadhas helped me, so far. And, I think more than 4 hours of unproductive searching for solution finally validates me to ask further help...

注意：到目前为止，该线程的任何答案都没有帮助过我。而且，我认为超过 4 个小时的徒劳的解决方案搜索最终使我能够寻求进一步的帮助......

I was following this tutorialin order to use a form in my Laravel project and allow me to save some user inputs in my database. As instructed, I executed this line via CMD:

我遵循本教程是为了在我的 Laravel 项目中使用表单并允许我将一些用户输入保存在我的数据库中。按照指示，我通过 CMD 执行了这一行：

composer require "laravelcollective/html":"^5.3.0"

Then, I've added these inside config/app.php:

然后，我在config/app.php 中添加了这些：

'providers' => [
// ...
  Collective\Html\HtmlServiceProvider::class,
// ...
],

'aliases' => [
// ...
  'Form' => Collective\Html\FormFacade::class,
  'Html' => Collective\Html\HtmlFacade::class,
// ...
],

In my view, I have this, just to check if everything is now ready to be used:

在我看来，我有这个，只是为了检查现在是否一切都可以使用：

{!! Form::open([]) !!}
{!! Form::text('name', @$name) !!}
{!! Form::password('password') !!}
{!! Form::submit('Send') !!}
{!! Form::close() !!}

But then, it gave me this error:

但是后来，它给了我这个错误：

FatalThrowableError in ProviderRepository.php line 146: Class 'Collective\Html\HtmlServiceProvider' not found

ProviderRepository.php 第 146 行中的 FatalThrowableError：找不到类“Collective\Html\HtmlServiceProvider”

I even added this to my composer.json, just in case this might be the "missing ingredient":

我什至将此添加到我的 composer.json，以防万一这可能是“缺少的成分”：

"require": {
    "laravel/framework": "5.0.*",
    "laravelcollective/html": "~5.0"
}

But it did not solve anything either.

但它也没有解决任何问题。

Please also note that I found two composer.json files: one inside...

另请注意，我发现了两个 composer.json 文件：一个在里面...

C:\xampp\htdocs\laravelproject

C:\xampp\htdocs\laravelproject

and another inside...

还有一个里面...

C:\xampp\htdocs\laravelproject\project

C:\xampp\htdocs\laravelproject\project

... so I edited both.

......所以我编辑了两者。

Side Note:The "project" folder is where the "original" root files can be found (e.g. the folders app, config, resources, etc.. I have previously relocated them in order to remove the word "public" from my URL.

边注：“项目”文件夹是可以找到“原始”根文件的地方（例如文件夹 app、config、resources 等。我之前已重新定位它们以从我的 URL 中删除“public”一词。

PS:I am very new to Laravel, Composer, and CMD. My only background is in PHP and CodeIgniter.

PS：我对 Laravel、Composer 和 CMD 都很陌生。我唯一的背景是 PHP 和 CodeIgniter。

Please help.

请帮忙。

I'm not sure if I should provide here the CMD result after running composer require "laravelcollective/html":"^5.3.0"(because it's 142 lines long), but I have a copy, just in case.

我不确定我是否应该在运行composer require "laravelcollective/html":"^5.3.0"后在这里提供 CMD 结果（因为它有 142 行长），但我有一份副本，以防万一。

Clearly, Laravel's Illuminate/Foundation/ProviderRepository.phpis nagging about the not-found provider:

显然，LaravelIlluminate/Foundation/ProviderRepository.php正在唠叨未找到的提供者：

138     /**
139      * Create a new provider instance.
140      *
141      * @param  string  $provider
142      * @return \Illuminate\Support\ServiceProvider
143      */
144     public function createProvider($provider)
145     {
146         return new $provider($this->app);
147     }

I've just successfully tested it on a brand new installation of Laravel 5.3. Follow this checklist:

我刚刚在全新安装的 Laravel 5.3 上成功测试了它。遵循这个清单：

1. Issue composer require "laravelcollective/html":"^5.3.0".
2. Verify that the vendor/laravelcollective/htmldirectory exists.
3. Verify that your composer.jsonfile has been updated and there's an entry for laravelcollective/htmlpackage in your dependencies (requireblock).
4. Add Collective\Html\HtmlServiceProvider::classto your providersarray of config/app.php.
5. Add 'Form' => Collective\Html\FormFacade::classand 'Html' => Collective\Html\HtmlFacade::classto your aliasesarray.
6. Confirm that the API exists: Issue a php artisan tinkercommand and try playing with Form::APIs. See if throws any errors.

1. 问题composer require "laravelcollective/html":"^5.3.0"。
2. 验证vendor/laravelcollective/html目录是否存在。
3. 验证您的composer.json文件是否已更新，并且laravelcollective/html您的依赖项（require块）中有一个package条目。
4. 添加Collective\Html\HtmlServiceProvider::class到您providers的config/app.php.
5. 添加'Form' => Collective\Html\FormFacade::class和'Html' => Collective\Html\HtmlFacade::class到您的aliases阵列。
6. 确认 API 存在：发出php artisan tinker命令并尝试使用Form::API。查看是否抛出任何错误。

You might have already done all these steps. If that's the case, just remove the package with a composer remove laravelcollective/htmlcommand and redo all the steps again.

您可能已经完成了所有这些步骤。如果是这种情况，只需使用composer remove laravelcollective/html命令删除包并重新执行所有步骤即可。

And most importantly, get an idea of where your project files reside. Get rid of that extra project/.

最重要的是，了解您的项目文件所在的位置。摆脱那个额外的project/.
