laravel 5.4-php artisan迁移命令不'；行不通

我有四个迁移文件，当我在命令行中运行

php artisan migrate

时，它会显示：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

无需迁移

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

我还尝试了使用php artisan migrate--database=vcp：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

数据库[vcp]未配置。

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

我在

.env

文件中使用了另一个数据库，并再次运行

php artisan migrate

命令：

Migration table created successfully.
Nothing to migrate. 

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

运行

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

php-artisan-migrate:refresh

，

php-artisan-migrate:reset

，

php-artisan-migrate:status

，

php-artisan-migrate--path=“database/migrations/migration_file”

这些消息来自何处

Nothing to rollback.
Nothing to migrate.
No migrations found

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

及

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

没有帮助

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *

     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
}

正如您在上述评论中所述，
更改直接在数据库上完成。然后
无需迁移。
正确

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

试着理解这个概念，迁移包含文件中的表结构，当您运行迁移时，这些表是在数据库中创建的。在迁移文件中进行更改时，必须再次运行迁移，以便将这些更改反映回数据库表。因此，流量为：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

migration file -> database table

不是

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
}

试着理解这个概念，迁移包含文件中的表结构，当您运行迁移时，这些表是在数据库中创建的。在迁移文件中进行更改时，必须再次运行迁移，以便将这些更改反映回数据库表。因此，流程是：

class AddColumnsToUsers extends Migration
   {
       /**

            $table->dropColumn('api_token');
        });
     }
} 

migration file -> database table

不是

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

以下是对我有效的方法：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

首先，删除所有数据库表，包括迁移表。
其次，AddColumnsToUsers文件的更新方法up（）如下所示：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

public function up()
    {
    DB::beginTransaction();
    try {

        Schema::table('users', function (Blueprint $table) {
            $table->string('status')->default('online');
            $table->string('api_token');
       });

    DB::commit();
    } catch (PDOException $e) {
        DB::rollBack();
        $this->down();
    }
}

这将检查数据库以查看表是否已经存在，如果不存在，则创建该表，如果存在，则回滚。
让我知道这是否有效。
以下是对我有效的方法：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

首先，删除所有数据库表，包括迁移表。
其次，AddColumnsToUsers文件的更新方法up（）如下所示：

<?php

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

class AddColumnsToUsers extends Migration
   {
       /**
         * Run the migrations.
         *
         * @return void
        */
       public function up()
      {
            Schema::table('users', function (Blueprint $table) {
                $table->string('status')->default('online');
                $table->string('api_token');
           });
       }

     /**
      * Reverse the migrations.
      *
      * @return void
     */
    public function down()
     {
         Schema::table('users', function (Blueprint $table) {
            $table->dropColumn('status');
            $table->dropColumn('api_token');
        });
     }
} 

public function up()
    {
    DB::beginTransaction();
    try {

        Schema::table('users', function (Blueprint $table) {
            $table->string('status')->default('online');
            $table->string('api_token');
       });

    DB::commit();
    } catch (PDOException $e) {
        DB::rollBack();
        $this->down();
    }
}

这将检查数据库以查看表是否已经存在，如果不存在，则创建该表，如果存在，则回滚。
让我知道这是否有效。
你的迁移文件看起来像什么，你给它们起了什么名字？我更改了我的数据库并再次运行了php artisan migrate命令：这些更改是在迁移文件中完成的还是直接在数据库中完成的？我使用
php artisan make:migration create_name_of_table创建了它们
你尝试过
php artisan migrate吗--path=“database/migrations”
？@Mayank Pandeyz直接在数据库上，除了migrations表和my migrations表是空的之外，数据库中不存在任何内容！你的迁移文件看起来像什么？你给它们起了什么名字？我更改了我的数据库并再次运行了php artisan migrate命令：这些更改是在迁移文件中完成的，还是直接在数据库中完成的？我用
php artisan make:migration create\u name\u of_table
创建了它们。你试过
php artisan migrate--path=“数据库/迁移”吗
？@Mayank Pandeyz直接在数据库上，数据库中除了迁移表之外什么都不存在，我的迁移表是空的！我理解这个概念，谢谢！但我不知道我的代码哪里出了问题。我仍然无法迁移我的迁移文件！我理解这个概念，谢谢！但我不知道我的代码哪里出了问题。我仍然无法迁移我的迁移文件！
