Question

我正在尝试构建一个表，但是当我运行此命令时＃34; php artisan migrate＆＃34;发生此错误：

[照亮\数据库\ QueryException]
  SQLSTATE [42S02]：找不到基表或视图：1146表＆＃39; epharmacy.medici
  未列名＆＃39;不存在（SQL：alter table medicines add id int unsigned not
  null auto_increment主键，添加name varchar（255）not null，添加typ e varchar（255）not null，添加potency varchar（255）not null，添加created _at timestamp null，添加updated_at timestamp null）

迁移：

<?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) {
            //
        });
    }
}

根据the docs，它必须是：

<?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');
    }

}

未找到基准表或视图：1146表＆＃39; epharmacy.medicines＆＃39;不存在
