php - Laravel:InvalidArgumentException:数据库 [mysql] 未配置

Question

为了让 Laravel 正常工作，我已经尝试了好几天。我无法弄清楚的当前问题是未配置的数据库。

.环境:

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

数据库.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,
    ],
],

我终于使用您日志中的信息重现了您的确切错误:

在我看来这像是一个语法错误，因此我无法说出它发生的原因。看看我做了什么来产生错误，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。可能你上传的文件和本地文件有差异。 connections 键一定有问题，或者之前某处的引号有问题。最好发布整个文件。
