文件:2017_03_04_201351_create_permission_role_table.php

<?php

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

class CreatePermissionRoleTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        /**
         * Run the migrations.
         *
         * @return void
         */
        Schema::create('permission_role', function (Blueprint $table) {
            $table->integer('permission_id')->unsigned()->index();
            $table->integer('role_id')->unsigned()->index();

            $table->foreign('permission_id')
                ->references('id')
                ->on('permissions')
                ->onDelete('cascade');

            $table->foreign('role_id')
                ->references('id')
                ->on('roles')
                ->onDelete('cascade');

            $table->primary(['permission_id', 'role_id']);
        });
    }

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

这是迁移..

我尝试了composer dump它也没有出现..

它拒绝迁移..

我手动删除，但在回滚后migrate:refresh或migrate时出现相同的错误。

最后就是错误:

  [Illuminate\Database\QueryException]
  SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'permission_role' already exists (SQL: create table `permission_role` (`permission_id` in
  t unsigned not null, `role_id` int unsigned not null) default character set utf8 collate utf8_unicode_ci)

  [PDOException]
  SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'permission_role' already exists

您已经拥有表permission_role，现在您的迁移表与您的数据库不对齐。

如果您知道该怎么做，您可以手动编辑迁移表，恢复您丢弃的文件并运行“composer dump-autoload”，然后进行迁移

可能最好的方法是手动删除所有表(包括迁移表)并重新运行迁移。如果您可以删除所有表格。
