【问题描述】：

我最近升级到节点 6、angular 4、typescript 2.3.2 和 @angular/cli 1.02。我关注了Guide，了解如何升级@angular/cli。如果那里有任何相关内容，我将在下面添加我的整个 package.json。我得到这个错误：

ERROR in AppModule is not an NgModule
ERROR in ./src/main.ts
Module build failed: TypeError: Cannot read property 'newLine' of undefined
at Object.getNewLineCharacter (C:\development\projects-git\mydoc\static-    web\node_modules\typescript\lib\typescript.js:9580:20)
at Object.createCompilerHost (C:\development\projects-git\mydoc\static-web\node_modules\typescript\lib\typescript.js:66674:26)
at Object.ngcLoader (C:\development\projects-git\mydoc\static-web\node_modules\@ngtools\webpack\src\loader.js:202:31)
 @ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts

在指南中，我必须将我的 main.ts 更新为：

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModule } from './app/app.module';

if (environment.production) {
  enableProdMode();
}

platformBrowserDynamic().bootstrapModule(AppModule);

我完整的package.json 是这样的：

}

这使得构建变得不可能。

【问题讨论】：

你能分享你的 AppModule.ts 吗？
我的 app.module.ts 是一个庞大的类，包含所有导入的模块、组件和服务。

标签： javascript angular typescript npm angular-cli

【解决方案1】：

这似乎是known issue。确保您的节点模块已正确重新安装：

rm -rf node_modules && npm cache clean && npm uninstall --save angular-cli && npm uninstall -g angular-cli && npm i --save @angular/cli && npm i -g @angular/cli && npm i
