【问题描述】：

我正在尝试在我的视图文件中呈现一个文本输入字段。我不断收到此错误：“在 view-file.blade.php 中找不到类 'form'”

模板：

@extends('layouts.app')

@section('content')
    <h1>New</h1>

    {{ Form::open() }}
        {{ Form::text('my-name') }}
    {{ Form::close() }}
@endsection

“作曲家秀”列出以下内容：

laravel/framework v5.5.19 The Laravel Framework
laravelcollective/html v5.5.1  HTML and Form Builders for the Laravel Framework

我已经尝试了其他 SO 问题中建议的一些事情，例如：

作曲家转储自动
php artisan 缓存：清除
php 工匠配置：清除

还是不行。提前致谢！

【问题讨论】：

曾经访问过这个link
当你标记你的问题时，我首先假设你使用的是 Laravel 5.5 是使用 5.5 of laravelcollective/html
@rahulsm 我完全按照链接所说的做了
@Marcin Nabialek：是的，'composer show' 说我使用的是 5.5 版本的 laravelcollective/html

标签： php laravel-5.5 laravelcollective

【解决方案1】：

安装 laravelcollective/html

composer require "laravelcollective/html":"^5.5"

更新作曲家

composer update

在config/app.php中添加Provider和Static Facade

<?php

'providers' => [

    Collective\Html\HtmlServiceProvider::class,

  ],

'aliases' => [

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

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

  ],

【讨论】：

感谢您的回答。我检查了安装了哪个版本的 laravelcollective 包，它是 5.5 的。所以，我认为我很好，但仍然收到错误:(
先直接从github.com/LaravelCollective/html下载，加入composer.json后放入vendor\laravelcollective文件夹
我已经编辑了我原来的问题。我已经更新了 composer.json 中的包版本（虽然我已经有 5.5.1 的 laravel 集体）我还为 laravel 框架和 laravel 集体包添加了“composer show”的输出。我已经检查了类是否存在（别名指向的）并且它们确实存在！所以这里仍然没有线索:(

【解决方案2】：

这可能是因为在 Composer 完成安装之前将其添加到 config/app 中。

尝试使用php artisan config:cache
