基表或視圖未找到：1146表「epharmacy.medicines」不存在

Question

我想建一個表，但是當我運行此命令「PHP工匠移民」這個錯誤發生：

[照亮\數據庫\ QueryException]
SQLSTATE [42S02]：基表或視圖未找到：1146表 'epharmacy.medici
未列名' 不存在（SQL：改變表medicines添加id INT無符號不
空AUTO_INCREMENT主鍵，加name varchar（255）不爲空，加typ
e varchar（255）不爲空，加potency varchar（255）not nul L，加created
_at時間戳空，加updated_at時間戳空）

遷移：

<?php 

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

class CreateMedicineTable extends Migration 
{ 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::table('medicines', function (Blueprint $table) { 
      $table->increments('id'); 
      $table->String('name'); 
      $table->String('type'); 
      $table->String('potency'); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::table('medicines', function (Blueprint $table) { 
      // 
     }); 
    } 
}

據the docs，它需要：

<?php 

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

class CreateMedicineTable extends Migration 
{ 
    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::create('medicines', function (Blueprint $table) { 
      $table->increments('id'); 
      $table->string('name'); 
      $table->string('type'); 
      $table->string('potency'); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::dropIfExists('medicines'); 
    }  

}
