Php 你知道它为什么会出现吗；BadMethodCallException方法[ValidateRequested]不存在；？

我有方法store（）为会议创建新的注册类型。但它似乎是一个错误“BadMethodCallException” 方法[validateEquired]不存在。“在文件“illumb/Validation/Validator.php”中”

你知道为什么吗

public function store(Request $request, $id)
{
    $rules = [
        'registration_type_name' => 'required',
        'registration_type_capacity' => 'required|integer|min:0',
        'registration_type_price' => 'required|integer|min:0',
        'registration_type_minimum' => 'equired|integer|min:1',
        'registration_type_maximum' => 'rgt:registration_type_minimum|required|integer|min:1',
    ];

    $customMessages = [
        'registration_type_name.required' => 'The field name is rqeuired.',
        'registration_type_capacity.integer' => 'The field capacity needs to be a positive integer.',
        ....
    ];

    $this->validate($request, $rules, $customMessages);
    $conference = Conference::find($id);


    RegistrationType::create([
        'name' => $request->registration_type_name,
        'description' => $request->registration_type_description,
        'capacity' => $request->registration_type_capacity,
        'price' => $request->registration_type_price,
        'min_participants' => $request->registration_type_minimum,
        'max_participants' => $request->registration_type_maximum,
        'conference_id' => $conference->id
    ]);

    Session::flash('success', 'Registration type created.');
    return redirect()->back();
}

此处缺少一个

r

：

'registration_type_minimum' => 'equired|integer|min:1',
                                ^
