angular - Typescript 类构造函数中“找不到名称”

Question

当我通过将导入的名称插入到构造函数的参数中来将服务注入(inject)到类中时，出现“找不到名称”错误。这种情况现在在我身上发生过几次，但我不知道如何解决它。任何对此的启发将不胜感激。这是我的例子:

import { Component } from '@angular/core';
import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { _ } from 'lodash';
import { RatesService } from '../../services/RatesService';
import { NavController } from 'ionic-angular';
import { Currencies } from '../../models/currencies.ts';

@Component({
    selector: 'page-rates',
    templateUrl: 'rates.html'
})

export class Rates {

constructor(public navCtrl: NavController,
        private ratesService: RatesService,
        private currencies: Currencies) { }
}

“货币”导致错误

Answer 1

typescript 编译器给了我们一个误导性的错误字符串。

更改:

 import { Currencies } from '../../models/currencies.ts';

至

 import { Currencies } from '../../models/currencies';
