Laravel: InvalidArgumentException : Database [mysql] not configured

Question

I've been trying for days now to get Laravel working. The current problem that I can't figure out is the database that is not being configured.

.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,
    ],
],

EDIT:

I finally got to reproduce your exact error by using the information from your log:

It looks to me like a syntax error, thus I cannot say why it is happening. Look what I did to produce the error, the quotations on the connections key:

'''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,
    ],

Please double check your config/database.php file. Maybe there are differences between your uploaded file and the local one. Something must be wrong with the connections key or something with the quotation somewhere before that. Best you post the whole file.
