I\'ve installed laravel 5 successfully by using this command:
composer create-project laravel/laravel test-laravel-5-project dev-develop --prefer-dist
Laravel is using .env file so change the .env file or change in the database.php file without env()
'mysql' => [
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'your database name',
'username' => 'your database username',
'password' => 'your database password',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => false,
]
