角6-属性'pwdMatchValidator'在'typeof CustomValidator'类型上不存在

Question

我收到此编译错误：

  

src / app / modules / auth / pages / register / register.component.ts（38,24）中的错误：错误TS2339：属性''pwdMatchValidator'在'typeof CustomValidator类型上不存在'。

它引用的代码是：

import { CustomValidator } from '@helpers/custom-validator';

...

ngOnInit() {
  this.form = new FormGroup({
    name: new FormGroup({
      first: new FormControl('', [Validators.required, Validators.minLength(2)]),
      last: new FormControl(''),
    }),
    email: new FormControl('', [Validators.required, Validators.email]),
    password: new FormControl('', Validators.required),
    confirmed: new FormControl('', Validators.required),
  }, CustomValidator.pwdMatchValidator);
}

我已经在`tsconfig.json>编译器选项>路径中声明了@helpers：

"paths": {
  ...
  "@helpers/*": ["./src/app/core/helpers/*"],
  ...
}

CustomValidator类包含：

import {FormGroup} from '@angular/forms';

export class CustomValidator {

  static pwdMatchValidator(frm: FormGroup) {
    return frm.get('password').value === frm.get('confirmed').value ? null : {'mismatch': true};
  }

}

Webstorm似乎没有找到方法的问题：

我想念什么？

尝试这样

ngOnInit() {
  this.form = new FormGroup({
    ...
  }, {validator: CustomValidator.pwdMatchValidator});
}
