php - Laravel - PHP - 通过作曲家安装 HTML 包失败

问题描述

我正在学习 Laravel PHP，我试图在 PHP 网页中显示一些内容，如图像和音频。但是，它没有显示任何图像，而只显示纯文本。所以我尝试通过将一些代码行粘贴到 composer.json 文件和 app.php 文件来安装一些 HTML 包，就像他们在Undefined namespace html (adding a css file to Blade) laravel中所说的那样。运行 XAMPP 后，我得到一个错误：

Class "Illuminate\Html\HtmlServiceProvider" not found

我的 PHP 版本是 8.0.8（最新），我的 Laravel 版本是 8.52.0 这是我在 composer.json 中的要求：

"require": {
        "php": "^7.3|^8.0",
        "fideloper/proxy": "^4.4",
        "fruitcake/laravel-cors": "^2.0",
        "guzzlehttp/guzzle": "^7.0.1",
        "laravel/framework": "^8.40",
        "laravel/tinker": "^2.5",
        "illuminate/html": "~5.0"
    },

这是 app.php 之一：

        /*
         * Laravel Framework Service Providers...
         */

解决方案

不要把这当作对你的攻击，但我一遍又一遍地看到这个问题真的很沮丧......

如果你对一个包有任何问题，总是去找真相的来源......在这种情况下，它会是 Packagist（它是作曲家包的官方“来源”），它会告诉你它来自哪里等等。 ..

所以，如果你这样做，它会带你到这里，你会看到一个美丽的红色传说：

此软件包已废弃且不再维护。作者建议改用laravelcollective/html包。

所以，你点击推荐的包，你会进入一个新的 Packagist 页面，在右侧（github）显示主 repo 。当你去那个页面时，你可以在自述文件中看到一个主页，所以你去那里。

在该页面中，您将看到的第一件事是与之相关的文档，它显示的第一个“元素”是HTML您要使用的那个（向您显示可用的文档版本laravelcollective/html）...

所以你点击那个，看看如何使用那个类/助手/服务......

还有一件事，因为 repo 或主页没有说明它支持的 Laravel 版本，所以请始终检查源代码的 composer 文件。你会看到它需要一些illuminate/xxxx: ^6.0|^7.0|^8.0，这意味着当前 Laravel 支持的版本是>= 6.x但不是<= 5.8。所以支持 Laravel 8。

该检查适用于任何具有 Laravel 版本约束的包。如果你没有看到任何这些，那么它应该可以被任何 Laravel 版本使用......
