laravel - 在 Laravel 中找不到类 'Illuminate\Foundation\Application'

Question

我真的不明白我的 Laravel 应用程序发生了什么。我从来没有碰过它 7-14 天，因为我需要专注于我的项目(用 CI 编写)。当我的项目完成后，我回到我的 Laravel 应用程序来探索更多关于它的信息。接下来发生的事情超出了我的想象。我的浏览器出现了这个错误:

Fatal error: Uncaught Error: Class 'Illuminate\Foundation\Application' not found in C:\xampp\htdocs\leadershipradar\bootstrap\app.php:14 Stack trace: #0 C:\xampp\htdocs\leadershipradar\public\index.php(23): require_once() #1 {main} thrown in C:\xampp\htdocs\leadershipradar\bootstrap\app.php on line 14

我搜索如何修复它。我在 stackoverflow 上发现了这个:

http://stackoverflow.com/questions/34172644/getting-error-class-illuminate-foundation-application-not-found-in-laravel-5

我遵循了所有指示，但一无所获。我还安装了新的 laravel 并复制了所有逻辑、模型、路由和 View 。但错误仍在发生。

我确实将 composer.json 文件更改为:

"require": {
    "php": ">=5.5.9",
    "laravelcollective/html": "5.1",
    "illuminate/routing": "5.1.1",
    "laravel/framework": "5.2.10",
    "illuminate/html": "^5.0"
},

当我运行 composer update 时，我的 cmd 中出现了新的错误。

请帮我解决这个问题。非常感谢。

附言:

这是我的 composer.json

你的 composer require block 给你带来了麻烦

自从你使用 laravel 5.2，你应该使用

"laravelcollective/html":"^5.2"并删除 "illuminate/html": "^5.0" taylor 不再维护此包
并删除 "illuminate/routing": "5.1.1" laravel/framwork 已经需要兼容的 illuminate/routing pacakge
