App\Models\Image 出错？

添加图片接口之前是正常的，今天调接口突然报错 Image 找不到，打开phpstorm发现语法报错
将原来的写法

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Image extends Model
{
    //
    protected $fillable = ['type', 'path'];

    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

改成

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Image extends Model
{
    //
    protected $fillable = array('type', 'path');

    public function user()
    {
        return $this->belongsTo(\App\Models\User);
    }
}

就好了，上周重装了homestead，php现在是7.2，原来的写法7.2不适用了吗
