Erro de template

Não sei o que pode ser, estava funcionando:

<div class="form-group">
                <label>Descrição</label>
                <textarea name="descricao" formControlName="descricao" [(ngModel)]="foto.descricao" class="form-control" autocomplete="off">
                </textarea>
            </div>

            <button nome="Salvar" tipo="submit" estilo="btn-primary" [desabilitado]="!meuForm.valid">
                Salvar
            </button>
            <a [routerLink]="['']" class="btn btn-primary">Voltar</a>
            <hr>
        </div>

<button (click)="executaAcao()" class="btn {{estilo}}" [type]="tipo" [disabled]="desabilitado">{{nome}}</button>

import { Component, Input, Output, EventEmitter } from '@angular/core';

@Component({
    moduleId: module.id,
    selector: 'botao',
    templateUrl: './botao.component.html'
})
export class BotaoComponent {

    @Input() nome: string = 'Ok';
    @Input() estilo: string = 'btn-default';
    @Input() tipo: string = 'button';
    @Input() desabilitado: boolean = false;
    @Output() acao = new EventEmitter();
    @Input() confirmacao: boolean = false;

    executaAcao() {

        if(this.confirmacao) {
            if(confirm('Tem certeza?')) {
                this.acao.emit(null); 
            }
            return; 
        }          
        this.acao.emit(null);
    }
}

Can't bind to 'desabilitado' since it isn't a known property of 'button'. ("

][desabilitado]="!meuForm.valid"> Salvar "): CadastroComponent@31:69 ; Zone: ; Task: Promise.then ; Value: Error: Template parse errors: Can't bind to 'desabilitado' since it isn't a known property of 'button'. ("

O mais estranho é que esse é o erro de console, no prompt tem outro erro:
