Laravel 4.2 Composer 安装错误："could not scan for classes"

6

我想在我的新Laravel 4.2安装中通过Composer安装一些包。然而，我遇到了一个异常。

这是我的Composer文件：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "license": "MIT",   
    "require": {
        "laravel/framework": "4.2.*",
        "zizaco/confide": "~4.0@dev",
        "zizaco/entrust": "1.2.*@dev",
        "barryvdh/laravel-ide-helper": "1.*",
        "fzaninotto/faker": "1.3.*@dev",
        "bllim/datatables": "~1.3",
        "barryvdh/laravel-debugbar": "~1.7"
    },
    "require-dev": {
        "way/generators": "~2.6",
        "barryvdh/laravel-ide-helper": "~1.11"
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php",
            "app/controllers/admin",
            "app/controllers/user"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd":[
            "php artisan ide-helper:generate"
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "stable"
}

运行composer install时，我收到以下提示：

$ composer install
Loading composer repositories with package information

n. You may be getting outdated dependencies. Run update to update them.

lugins] [--no-custom-installers] [--no-scripts] [--no-progress] [-v|vv|vvv|--ver
bose] [-o|--optimize-autoloader] [packages1] ... [packagesN]

这基本上是一个全新的Laravel安装。为什么我会收到错误提示：

Could not scan for classes inside "app/controllers/admin" which does not appear to be a file nor a folder

更新

使用composer update命令：

$ composer update

对于2021年的Laravel 8，如果不存在admin文件夹，请在控制器中添加该文件夹，并且进入composer.json并将classmap进行更改。

  "classmap": [
        "app/http/controllers/admin"
    ]

尝试使用composer update命令。这就是错误信息中提示的方法。

...You may be getting outdated dependencies. Run update to update them...

更新：

Composer 正在尝试查找 app/controllers/admin 文件夹，但这不是 Laravel 中的标准文件夹。你确定这个文件夹存在吗？如果不存在，你可以尝试从 composer.json 中移除这些自定义文件夹，并手动添加它们。你也可以创建这些目录并保持 composer.json 不变。
