Laravel - SQLSTATE [42000]:语法错误或访问冲突:迁移时为1064

Question

我从来没有遇到这个错误,直到现在它发生在我运行php artisan migrate
我正在使用MySQL 5.6.34
我尝试了我能想到的一切):并且仍然没有运气我有一个类似的表这个并且工作正常但是对于一些原因,这曾经不起作用

[PDOException]
  SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax
  to use near 'unsigned not null, `address_1` varchar(191) unsigned not null, `address_2` varch' at line 1

这是我的迁移文件

public function up()
    {
        Schema::create('rmaRequests', function (Blueprint $table) {
           $table->increments('id');
           $table->integer('user_id')->unsigned();
           $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
           $table->string('reference_number')->unique();
           $table->string('first_name');
           $table->string('last_name');
           $table->string('email');
           $table->string('phone');
           $table->string('fax');
           $table->string('company');
           $table->integer('marketplaceId')->unsigned();
           $table->string('order_number')->unsigned();
           $table->string('address_1');
           $table->string('address_2');
           $table->string('city');
           $table->string('state');
           $table->string('zip');
           $table->integer('returnTypeId')->unsigned();
           $table->string('sku');
           $table->string('qty');
           $table->string('productName');
           $table->text('comments');
           $table->integer('status_id')->unsigned();
           $table->string('replacement_tracking');
           $table->string('return_tracking');
           $table->string('rma_number');
           $table->string('refund_number');
           $table->timestamps();
        });
    }



/**

     */
    public function down()
    {
        Schema::drop('rmaRequests');
    }

我想这是因为你用unsigned的varchar？

这里:

$table->string('order_number')->unsigned();

unsigned()Laravel描述中的方法:

将integer列设置为UNSIGNED
