＆＃39;找不到名字＆＃39;在Typescript类构造函数中

Question

我找不到名字＆＃39;通过将导入的名称插入构造函数的参数中将服务注入到类中时出错。这已经发生在我身上几次，我无法弄清楚是什么解决了它。任何关于此的光线都将非常受欢迎。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) { }
}

＆＃39;货币＆＃39;导致错误

Answer 1

typescript编译器给我们一个误导性的错误字符串。

变化：

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

到

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