我正在学习Angular 2,我收到一个奇怪的错误：
ERROR in [default] /home/szabo/PHPstormProjects/recipe-book/src/app/recipes/recipe-list/recipe-item.component.ts:11:2
Unable to resolve signature of property decorator when called as an expression.
Supplied parameters do not match any signature of call target.
这是我的“模特”：
recipe.ts
export class Recipe {
constructor(public name,public description,public imagePath) {
}
}
这是我的RecipeItemComponent：
import {Component,OnInit,Input} from '@angular/core';
import { Recipe } from '../recipe';
@Component({
selector: 'app-recipe-item',templateUrl: './recipe-item.component.html',styleUrls: ['./recipe-item.component.css']
})
export class RecipeItemComponent implements OnInit {
@Input recipe: Recipe; //line 11
recipeId: number;
constructor() { }
ngOnInit() {
}
}
可能是什么问题呢？
谢谢.
解决方法
你的模型不是问题,你在@Input装饰器上缺少()：
@Input() recipe: Recipe;
