There is something wrong with transpile process

Ionic Framework ionic-v3
1

I’m having a little strage issue.
I’ve create an class called Classe.

import { diceENUM } from '../diceENUM';
import { classeENUM } from './classesEnum';

export class Classe {
    private classe: classeENUM;
    private nivel: number;
    private dadoDeVida: diceENUM;

    constructor($classe: classeENUM, $nivel: number, $dadoDeVida: diceENUM) {
        this.classe = $classe;
        this.nivel = $nivel;
        this.dadoDeVida = $dadoDeVida;
    }
    public get $nome(): string {
        switch (this.classe) {
            case 0:
                return 'Clerigo';
            case 1:
                return 'Homem de Armas';
            case 2:
                return 'Mago';
            case 3:
                return 'Ladino';
        }
    }
    public get $classe(): classeENUM {
        return this.classe;
    }
    public set $classe(classe : classeENUM){
        this.classe = classe;
    }
    public get $nivel(): number {
        return this.nivel;
    }
    public set $nivel(nivel : number){
        this.nivel = nivel;
    }
    public get $dadoDeVida(): diceENUM {
        return this.dadoDeVida;
    }
    public set $dadoDeVida(dadoDeVida : diceENUM){
        this.dadoDeVida = dadoDeVida;
    }
}

Ok, nothing wrong about it.
Then I created an class called Mago that extends Classe.

import { Classe } from './classe';
import { BonusDeClasse } from '../constantesClass';
import { AcessoMagia } from '../constantesClass';
import { ConstantesClass } from '../constantesClass';

export class Mago extends Classe{
    constructor(nivel: number){
        super(2, nivel, 4)
    }
    public get $bonus() : BonusDeClasse {
        if (this.$nivel <= 0) {
            return null;
        } else {
            let bonus = ConstantesClass.MAGO_BONUS;
            for (var index = 0; index < bonus.length; index++) {
                if (this.$nivel === bonus[index].nivel) {
                    return bonus[index];
                }
            }
            return null;
        }
    }
    public get $magia() : AcessoMagia {
        if (this.$nivel <= 0) {
            return null;
        } else {
            let bonus = ConstantesClass.MAGO_MAGIA;
            for (var index = 0; index < bonus.length; index++) {
                if (this.$nivel === bonus[index].nivel && bonus[index].acessoMagia.length === 9 ) {  
                    return bonus[index];
                }
            }
            return null;
        }
    }
}

Ok, nothing wrong about it neither…
But, I’ve created another class called HomemDeArmas that extends Classe.
And type ionic serve.
And on transpiling it return this error:

 typescript: D:/Estudos/example/src/classes/homemdearmas.ts, line: 5
 Type 'any' is not a constructor function type.

Follow the code of HomemDeArmas bellow:

import { Classe } from './classe';
import { BonusDeClasse } from '../constantesClass';
import { ConstantesClass } from '../constantesClass';

export class HomemDeArmas extends Classe{

    constructor(nivel: number){
        super(1, nivel, 10)
    }

    public get $bonus() : BonusDeClasse {
        if (this.$nivel <= 0) {
            return null;
        } else {
            let bonus = ConstantesClass.MAN_AT_ARMS_BONUS;
            for (var index = 0; index < bonus.length; index++) {
                if (this.$nivel === bonus[index].nivel) {
                    return bonus[index];
                }
            }
            return null;
        }
    }

}

I Just can’t find any logic about this error.
Maybe it’s just a simple thing to correct
