Question

当我想要php artisan migrate 时出现此错误。错误信息如下

   Illuminate\Database\QueryException

SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' already exists (SQL: create table users (id bigint unsigned not null auto_increment primary key, name varchar(255) not null, email varchar(255) not null, email_verified_at timestamp null, password varchar(255) not null, remember_token varchar(100) null, created_at timestamp null, updated_at timestamp null) default character set utf8mb4 collate 'utf8mb4_unicode_ci')

数据库设置如下。 Database.php文件中设置如下

 'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'laravel'),
            'username' => env('DB_USERNAME', 'root'),
            'password' => env('DB_PASSWORD', ''),
            'unix_socket' => env('DB_SOCKET', ''),
            'charset' => 'utf8mb4',
            'collation' => 'utf8mb4_unicode_ci',
            'prefix' => '',
            'prefix_indexes' => true,
            'strict' => true,
            'engine' => null,
            'options' => extension_loaded('pdo_mysql') ? array_filter([
                PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
            ]) : [],
        ],

.env文件中的设置如下

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:sBKduFaKhOJdg7/A1U4IzAUnj3yLLcjngjmMvEoWl94=
APP_DEBUG=true
APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=

注意:我使用 mysql 作为 wampserver。
