Laravel 4.2 Composer安装错误:“无法扫描类" [英] Laravel 4.2 Composer install error: "could not scan for classes"

问题描述

我想通过Composer在新的Laravel 4.2安装中安装一些软件包.但是，我要例外了.

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

这是我的Composer文件:

This is my Composer file:

{
    "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，我得到:

$ composer install
Loading composer repositories with package information

Warning: The lock file is not up to date with the latest changes in composer.jso
n. You may be getting outdated dependencies.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.为什么会出现错误:

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

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

推荐答案

尝试使用composer update.这就是错误中的意思.

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

...You may be getting outdated dependencies.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

更新:

Composer试图找到文件夹app/controllers/admin，它在laravel中不是标准文件夹.您确定此文件夹存在吗?如果没有，您可以尝试从composer.json中删除这些文件夹以及其他自定义文件夹，然后手动添加它们.您还可以创建目录，并保持composer.json不变.

Composer is trying to find the folder app/controllers/admin which 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.
