php - SQLSTATE[42S01] : Base table or view already exists or Base table or view already exists: 1050 Table

Question

这是我的迁移表

    <?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUserTable extends Migration
{

    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('role_id')->unsigned();
            $table->string('name');
            $table->string('email',50)->unique();
            $table->string('username');
            $table->string('password');
            $table->boolean('active');
            $table->rememberToken();
            $table->timestamps();

        });
    }

    public function down()
    {
        Schema::dropIfExists('users');
    }
}

每当我尝试迁移时都会发生以下错误

*[照亮\数据库\QueryException] SQLSTATE[42S01]:基表或 View 已存在:1050 表“用户”已存在 ady 存在(SQL:创建表 users ( id int unsigned not null auto_incr ement 主键，role_id int 无符号非空，name varchar(191) 不 空，email varchar(50) 不为空，username varchar(191) 不为空，pas sword varchar(191) 不为空，active tinyint(1) 不为空，remember_token varchar(100) 空, created_at时间戳为空，updated_at时间戳 nu ll) 默认字符集utf8mb4 collat​​e utf8mb4_unicode_ci)

[PDO异常] SQLSTATE[42S01]:基表或 View 已存在:1050 表“用户”已存在 ady 存在*

请告诉我我该怎么办？我已经使用 migrate:reset 或 dumpautoload 或 rollback 没有任何反应。我花了很多时间编辑或删除这个用户文件并重新创建它。

尝试这样

   <?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUserTable extends Migration
{

    public function up()
    {
        Schema::dropIfExists('users');
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('role_id')->unsigned();
            $table->string('name');
            $table->string('email',50)->unique();
            $table->string('username');
            $table->string('password');
            $table->boolean('active');
            $table->rememberToken();
            $table->timestamps();

        });
    }

    public function down()
    {
        Schema::dropIfExists('users');
    }
}
