node.js - 当我通过 ng build --prod Angular 4.3.2 部署时出错

Question

我已将 Angular 从 4.0.0 升级到 4.3.2:

npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest @angular/animations@latest typescript@latest rxjs@latest --save

然后我放置了 ngserve 并运行良好，但是当我想通过 ng build --prod 进行部署时，出现以下错误:

我还显示文件内容:main.ts

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

我在网上查了一下这个问题，但没有找到解决的原因。可能缺少什么？

Answer 1

几天后我通过 package.json 中的以下内容解决了 $$_gendir 问题:

• typescript 版本 2.3.3(“ typescript ”:“~2.3.3”)
• 脚本/产品:“ng build --env=prod --aot=true”

主要问题是 typescript 版本错误。
