yii2高级编解码器图像上载失败，出现错误'；无效配置$uploadDir'；

尝试使用Redactor获得Yi2高级工作，文本区域可以显示，但图像插入失败。始终获取错误帖子并获取错误500。 我已经在Yii2Web上使用UploadedFile教程进行了测试，图像可以成功上传并显示在目录中，但redactor无法工作

以下是我的文章：

namespace backend\controllers;

use yii\web\Controller;
use common\models\Article;
use Yii;

class ArticleController extends Controller{

    public $layout='empty';

    public function actionIndex(){
        $model = new Article;

        if($model->load(Yii::$app->request->post()) && $model->validate()){
            echo  "good operation";
        }
        return $this->render('index', ['model'=>$model]);
    }

这是我的模型：

namespace common\models;

use yii\db\ActiveRecord;
use Yii;

class Article extends ActiveRecord{

    //const SCENARIO_LOGIN = 'login';
    //const SCENARIO_REGISTER = 'register';

    public static function tableName(){
        return '{{%article}}';
    }

    public function rules(){
        return [
            [['title','description','content'],'required','message'=>'{attribute} required'],
            ['title','unique','message'=>'sorry，{value} is taken'],
            ['status','in','range'=>[0,1]],
            ];
    }


}

和视图：

<?php
use yii\helpers\Url;
use yii\widgets\Breadcrumbs;
use yii\helpers\Html;
use yii\widgets\ActiveForm;
?>

<?=Breadcrumbs::widget([
    'homeLink'=> ['label'=>'Home'],
    'links'=> [
            ['label'=>'Add New Article'],
        ],
])?>

    <?php
    $form = ActiveForm::begin([
            'id'=>'article',
            'options'=>['class'=>'wenzhang'],
        ]);
    ?>
    <?=$form->field($model, 'title')?>
    <?=$form->field($model,'description')?>
    <?=$form->field($model,'content')->widget(\yii\redactor\widgets\Redactor::className(),
        [
            'clientOptions'=>[
                    'imageManagerJson' =>['/redactor/upload/image-json'],
                    'lang'=>'zh_cn',
                    'plugins'=>['clips','fontcolor','imagemanager'],
                    'imageUpload' => \yii\helpers\Url::to(['/redactor/upload/image']),
                ],    
        ]
        )?>

    <button>Submit</button>
    <?php ActiveForm::end()?>

然后我转到Redactor模块检查配置：

   public $controllerNamespace = 'yii\redactor\controllers';
    public $defaultRoute = 'upload';
    public $uploadDir = '@webroot/uploads'; 
    public $uploadUrl = '@web/uploads';
    public $imageUploadRoute = ['/redactor/upload/image'];
    public $fileUploadRoute = ['/redactor/upload/file'];
    public $imageManagerJsonRoute = ['/redactor/upload/image-json'];
    public $fileManagerJsonRoute = ['/redactor/upload/file-json'];
    public $imageAllowExtensions = ['jpg', 'png', 'gif', 'bmp', 'svg'];

一切似乎都设置正确，在/web/uploads上，我已经成功地在先前的UploadedFile测试中上传了图像。

此外，多次尝试手动分配索引“ClientOptions”上的目录，问题仍然存在

更新小部件的版本，如您在此处所见

，开发者进行一些更改以防止此错误

谢谢，您的链接解决了问题。我只是想知道我用关键词搜索过谷歌，那个页面没有搜索结果，你是怎么找到的。嗯，我在github repo中找到了这个错误文本，并发现开发人员更改代码以防止错误。

   public $controllerNamespace = 'yii\redactor\controllers';
    public $defaultRoute = 'upload';
    public $uploadDir = '@webroot/uploads'; 
    public $uploadUrl = '@web/uploads';
    public $imageUploadRoute = ['/redactor/upload/image'];
    public $fileUploadRoute = ['/redactor/upload/file'];
    public $imageManagerJsonRoute = ['/redactor/upload/image-json'];
    public $fileManagerJsonRoute = ['/redactor/upload/file-json'];
    public $imageAllowExtensions = ['jpg', 'png', 'gif', 'bmp', 'svg'];
