SQLSTATE [HY000] [1045]拒绝访问用户'mamim'@'localhost'（使用密码：YES）

I am new to Laravel framework. I keep getting this error when trying to write php artisan serve in terminal. I am not able to do somethings .Below is the info I have in my .env file.

'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', 'localhostphp artisan make:migration create_users_table
'),
            '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' => false,
            'engine' => null,
        ],

and my .env file

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=mamim
DB_USERNAME=mamim
DB_PASSWORD=password

I tried to clear cahce but I met always the same error; SQLSTATE[HY000] [1045] Access denied for user 'mamim'@'localhost' (using password: YES)

Change 'host' => env('DB_HOST', 'localhostphp artisan make:migration create_users_table'), to 'host' => env('DB_HOST', 'localhost'), then try it.

Can you log into the mysql database with those credentials on the command line or in a MySQL GUI (like phpmyadmin, SequelPro, etc)?
