完成我的项目后，我将 mysql 切换到 mongodb。我正在使用 Laravel 5.4 版本，对于 mongodb 使用jenssegers。对于 laravel mongdb 安装，我遵循 jenssegers 安装文档并成功完成安装。但是安装后我去迁移并使用命令php artisan migrate。当我使用此命令时显示错误InvalidArgumentException in /vendor/mongodb/mongodb/src/Database.php line 83: $databaseName is invalid:

我的数据库.php

'default' => env('DB_CONNECTION', 'mongodb'),

'connections' => [

    'sqlite' => [
        'driver' => 'sqlite',
        'database' => env('DB_DATABASE', database_path('database.sqlite')),
        'prefix' => '',
    ],

    'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],

    'pgsql' => [
        'driver' => 'pgsql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '5432'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8',
        'prefix' => '',
        'schema' => 'public',
        'sslmode' => 'prefer',
    ],
    'mongodb' => [
        'driver'   => 'mongodb',
        'host'     => env('DB_HOST', 'localhost'),
        'port'     => env('DB_PORT', 27017),
        'database' => env('DB_DATABASE', 'project_db'),
        'username' => env('DB_USERNAME'),
        'password' => env('DB_PASSWORD'),
        'options'  => [
            'database' => 'admin' // sets the authentication database required by mongo 3
        ]
    ],

],

我的 .env

DB_CONNECTION=mongodb
DB_HOST=localhost
DB_PORT=27017
DB_DATABASE=admin
DB_USERNAME=
DB_PASSWORD=

.env如果我改变什么，database.php如果我将端口更改27017为3303但在浏览器显示上，我也会面临另一个问题27017。我清除了缓存和所有。我不知道我的代码有什么问题。

这些是 Envoyer（由 Laravel 的创建者制作）在生产中部署应用程序所采取的步骤——我在下面对它们进行了注释：

# Clear the old boostrap/cache/compiled.php
php artisan clear-compiled

# Recreate boostrap/cache/compiled.php
php artisan optimize

# Migrate any database changes
php artisan migrate
