在上面，我试图编写一个名为import { Component } from '@angular/core';
import { environment } from '../environments/environment';
const template = environment.production ? '../dev/dev-app.component.html' : './app.component.html';
@Component({
selector: 'app-root',
templateUrl: template,
styleUrls: ['./app.component.scss']
})
export class AppComponent {
title = 'app';
}
的条件变量，它将加载组件的视图。
仅出现以下错误：
./src/app/app.component.ts中的错误
找不到模块：错误：无法解析'/ src / app'中的'模板'
