node.js - 将服务器端代码添加到 angular-cli 项目与 Node 类型冲突

Question

添加基本 express.js 时配置(使用 TypeScript)到使用 angular-cli ng new [project-name] 初始化的 Angular2 项目，我需要添加以下类型以使用 gulp 编译 express 服务器:

typings install --ambient --save node

这会将以下行添加到 typings/browser.d.ts 和 typings/main.d.ts

/// <reference path="browser/ambient/node/index.d.ts" />
and
/// <reference path="main/ambient/node/index.d.ts" />

在快速 server.ts 文件中，我可以添加对 main 的引用而不是 browser 以保持 TypeScript 的快乐

/// <reference path="../typings/main.d.ts" />

但是当我在 browser.d.ts 文件中留下 Node 类型引用时，ng build 命令将失败:

Build failed.
The Broccoli Plugin: [BroccoliTypeScriptCompiler] failed with:

我现在可以在 browser.d.ts 中删除该行，以便它再次开始工作，但在重新安装打字时这并不理想。我目前正在使用 angular-cli v1.0.0-beta.0

Answer 1

实际错误源自 src/typings.d.ts 文件。 Angular-cli 使用以下内容创建此 typings.d.ts 文件:

/// <reference path="../typings/browser.d.ts" />
declare var module: { id: string };

删除此文件解决了问题，应用程序仍在运行。
