没有导出的成员/节点模块 [英] No Exported Member / Node Modules

问题描述

我只是使用在此处找到的5分钟快速入门来启动Angular 2/Typescript.我遇到了一个看似常见的问题，但可能有所不同.我遇到了各种各样的无出口会员"问题.例子:

I am just starting Angular 2 / Typescript using the 5 Minute Quickstart found here. I've run into what looks to be a common problem, but maybe a bit different. I am encountering all sorts of "No Exported Member" problems. Examples:

来自app.module.ts:

From app.module.ts:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

返回

...node_modules/@angular2/core/index" has no exported member 'NgModule'.

和

...@angular/platform-browser/index" has no exported member 'BrowserModule'.

并且来自main.ts:

And from main.ts:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

抛出:

...@angular/platform-browser-dynamic/index" has no exported member 'platformBrowserDynamic'.

我正在运行节点版本4.4.7和npm版本3.10.5.

I am running node version 4.4.7 and npm version 3.10.5.

我知道，在本教程的上下文中，通过将node或npm回滚到与本教程相关的版本，可以解决这些问题.我想我更想解释的是如何使教程中的代码与当前版本的节点相关.

I understand that these are probably resolvable in the context of the tutorial by rolling back node or npm to version relevant to the tutorial. I guess what I would prefer to have is an explanation of how to make the code from the tutorial relevant to the current versions of node.

ETA:这些错误发生在编译时，而不是执行时.

ETA: These errors occur at compilation, not execution.

推荐答案

NgModule类是通过node_modules/@angular/core/index.d.ts文件从node_modules/@angular/core/src/metadata.d.ts文件导出的.

The NgModule class is exported from the node_modules/@angular/core/src/metadata.d.ts file through the node_modules/@angular/core/index.d.ts one.

我想知道您是否在tsconfig.json文件中正确指定了moduleResolution属性:

I wonder if you specify correctly the moduleResolution property in your tsconfig.json file:

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node", // <-----
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  }
}
