Laravel：InvalidArgumentException：未配置数据库[mysql]

时间：2018-12-06 13:54:11

标签： php mysql laravel

我已经想了好几天让Laravel工作。我无法确定的当前问题是未配置的数据库。

.env：

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laracms
DB_USERNAME=homestead
DB_PASSWORD=secret

database.php：

'connections' => [
    'mysql' => [
        'driver'      => 'mysql',
        'host'        => env( 'DB_HOST', '127.0.0.1' ),
        'port'        => env( 'DB_PORT', '3306' ),
        'database'    => env( 'DB_DATABASE', 'laracms' ),
        'username'    => env( 'DB_USERNAME', 'homestead' ),
        'password'    => env( 'DB_PASSWORD', 'secret' ),
        'unix_socket' => env( 'DB_SOCKET', '' ),
        'charset'     => 'utf8mb4',
        'collation'   => 'utf8mb4_unicode_ci',
        'prefix'      => '',
        'strict'      => true,
        'engine'      => null,
    ],
],

我终于要通过使用日志中的信息来重现您的确切错误：

在我看来，这是一个语法错误，因此我无法说出它为什么发生。看看我是怎么产生错误的，connections键上的引号：

'''connections''' => [

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

    'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],

请仔细检查您的config/database.php文件。您上传的文件和本地文件之间可能存在差异。 connections键有问题或在此之前某处用引号引起了错误。最好您发布整个文件。
