Question

我正在尝试安装jenssegers Laravel-MongoDB软件包。（https://github.com/jenssegers/Laravel-MongoDB）

当我尝试composer update时，我收到以下错误：

"error":{"type:"ReflectionException","message":"Classs db does not exist","file":"C:\\wamp\\www\\projectname\\vendor\\laravel\\framework\\src\\Illuminate\\Container\\Container.php","line":308}} Script php artisan clear-compiled handling the post-update-cmd event returned with an error

我的composer.json文件如下所示：

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

    "require": {
        "laravel/framework": "4.0.*",
        "jenssegers/mongodb": "*"       
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "dev"
}

有任何建议如何解决这个问题？

Answer 1

像这样

    'Illuminate\Validation\ValidationServiceProvider',
    'Illuminate\View\ViewServiceProvider',
    'Illuminate\Workbench\WorkbenchServiceProvider',

    'Jenssegers\Mongodb\MongodbServiceProvider',

Answer 2

您是否在代码中使用db而不是DB？使用大写DB。另外，检查是否需要使用\ DB而不是DB，这可能是由于尝试在另一个非全局命名空间中使用数据库外观。

Answer 3

您只需执行以下命令即可成功安装。它对我有用。

要安装MongoDB，请按照

进行操作

- ＆gt; sudo -s - ＆gt; apt-key adv --keyserver hkp：//keyserver.ubuntu.com:80 --recv 7F0CEB10 echo＆＃39; deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen＆＃39; | sudo tee /etc/apt/sources.list.d/mongodb.list

- ＆gt; apt-get update - ＆gt; apt-get -y install mongodb-org

- ＆gt; grep -q＆＃34; extension = mongo.so＆＃34; /etc/php5/apache2/php.ini || echo＆＃34; extension = mongo.so＆＃34; ＆GT;＆GT; /etc/php5/apache2/php.ini

- ＆gt; grep -q＆＃34; extension = mongo.so＆＃34; /etc/php5/cli/php.ini || echo＆＃34; extension = mongo.so＆＃34; ＆GT;＆GT; /etc/php5/cli/php.ini& amp ;& amp; pecl install mongo

- ＆gt; echo＆＃34; extension = mongo.so＆＃34; ＆GT;＆GT; /etc/php5/cli/php.ini
