Javascript 方法[ValidateEnumberic]不存在

我的控制器是-

public function handleHome(Request $request) {
  $input = $request - > all();
  $validator = Validator::make($input, [
    'a' => 'required|max:255',
    'b' => 'required|numberic',
    'c' => 'required',
  ], [
    'required' => 'Bat buoc phai nhap',
    'numberic' => 'Can nhap so',
  ]);
  if ($validator - > fails()) {
    return redirect('home') -
      >
      withErrors($validator) -
      >
      withInput();
  } else {
    return redirect('home') - > with('message', 'everthing is good');
  }
}

将

numeric

更改为

numeric

：

'b' => 'required|numeric',
