打字稿错误：缺少私有财产？

我有一个带有私有属性的类，但是当我尝试使用此元素创建一个数组时，出现以下错误：

error TS2322: Type '{ "id": number; "totalTime": number; "team": { "id": number; "name": string; }; }[]' is not assignable to type 'Training[]'.
[0]   Type '{ "id": number; "totalTime": number; "team": { "id": number; "name": string; }; }' is not assignable to type 'Training'.
[0]     Property 'remainingTime' is missing in type '{ "id": number; "totalTime": number; "team": { "id": number; "name": string; }; }'

数组类：

import { TEAMS } from './mock-teams';
import { Training } from './training';

export var TRAININGS: Training[] = [ 
    {"id": 0, "totalTime": 60, "team": {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] } },
    {"id": 1, "totalTime": 60, "team": {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] } }
];

培训班：

export class Training {
    private remainingTime: number = 0;

    constructor(
        public id: number,
        public totalTime: number,
        public team?: Team) {
    }   
}

我不明白为什么打字稿抱怨的私有属性，甚至没有在构造函数中。

这样做的方法是创建一个Object []类型的数组。您需要做的是像下面这样调用构造函数，以告诉编译器您正在创建一个Training对象：

import { TEAMS } from './mock-teams';
import { Training } from './training';

export var TRAININGS: Training[] = [ 
    new Training(0,60, {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] }),
    new Training(1,60, {"id": TEAMS[0]['id'], "name": TEAMS[0]['name'] })
];
