Laravel 4.2 Composer 安装错误：“无法扫描类”

Laravel 4.2 Composer install error: "could not scan for classes"

提问by Anna.Klee

I want to install on my new Laravel 4.2 installation some packages via Composer. However, I am getting an exception.

我想通过 Composer 在我的新 Laravel 4.2 安装上安装一些软件包。但是，我得到了一个例外。

This is my Composer file:

这是我的作曲家文件：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "license": "MIT",   
    "require": {

        "zizaco/confide": "~4.0@dev",
        "zizaco/entrust": "1.2.*@dev",

    },

            "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"
}

When running composer installI get:

运行时composer install我得到：

$ composer install

This is basically a fresh Laravel installation. Why do I get the error:

这基本上是一个全新的 Laravel 安装。为什么我收到错误：

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

Try using composer update. That is what it says in the error.

尝试使用composer update. 这就是它在错误中所说的。

...You may be getting outdated dependencies.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

Update:

更新：

Composer is trying to find the folder app/controllers/adminwhich is no standard folder in laravel. Are you sure this folder exists? If not, you could try removing these, and other custom folders, from the composer.json, and add them manually. You could also create the directories and leave the composer.json untouched.

Composer 正在尝试app/controllers/admin在 laravel 中找到不是标准文件夹的文件夹。你确定这个文件夹存在吗？如果没有，您可以尝试从 composer.json 中删除这些和其他自定义文件夹，并手动添加它们。您还可以创建目录并保持 composer.json 不变。
