没有发现任何迁移

Question

我在codeigniter中创建迁移。但是我收到一条错误消息，说找不到迁移。我咨询了官方codeigniter文档。但在谷歌，我找不到这个错误。

我创建了迁移文件夹并添加了以下文件。 001_Create_users.php

 <? php
 /**
  * Description of 001_create_users
  *
  * @author Isuru
  */
 class Migration_Create_users extends CI_Migration {

   public
   function up() {
     $this - > dbforge - > add_field('id');
     $this - > dbforge - > add_field(array(
       'id' => array(
         'type' => 'INT',
         'constraint' => 11,
         'unsigned' => TRUE,
         'auto_increment' => TRUE
       ),
       'email' => array(
         'type' => 'VARCHAR',
         'constraint' => '100',
       ),
       'password' => array(
         'type' => 'VARCHAR',
         'constraint' => '100',
       ),
       'name' => array(
         'type' => 'VARCHAR',
         'constraint' => '100',
       ),
     ));
     //$this->dbforge->add_key('id', TRUE);
     $this - > dbforge - > create_table('users');
   }

   public function down() {
     $this - > dbforge - > drop_table('users');
   }

 }

这是migration.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

/*

| Enable/Disable Migrations
|--------------------------------------------------------------------------
|
| Migrations are disabled by default for security reasons.
| You should enable migrations whenever you intend to do a schema migration
| and disable it back when you're done.
|
*/
$config['migration_enabled'] = TRUE;

/*

| a timestamp. Options are:

|   'timestamp'  = Timestamp migration naming (20121031104401_add_blog.php)
|                  Use timestamp format YYYYMMDDHHIISS.

*/
$config['migration_type'] = 'timestamp';

$config['migration_table'] = 'migrations';

/*

| in your code to have the latest migration.
|
*/
$config['migration_auto_latest'] = TRUE;

/*

| This is used to set migration version that the file system should be on.
| If you run $this->migration->current() this is the version that schema will

|
*/
$config['migration_version'] = 1;

/*

|
| Path to your migrations folder.
| Typically, it will be within your application path.

*/
$config['migration_path'] = APPPATH.'migrations/';

我从昨天开始尝试找到解决方案，但我找不到解决方案。
