Angular2尝试启动项目时显示错误？

Question

我不知道为什么会发生这个错误。我的项目早些时候运行良好，我已经在项目目录之外全局安装了一些包（如 gulp 和 yo 生成器）。当我停止我的项目并重新启动它时，它显示以下错误。节点服务器仍在运行，但是当我使用 npm run tsc: -w 时，终端中会出现以下错误。

我使用 npm start，它是 package.json 中的一个脚本：

"start": "tsc && concurrently \"npm run tsc:w\" \"node server/index.js\" ",

Answer 1

您是否正确安装了类型？

1. 通过 npm 全局安装 - $ npm install typings --global

2. 然后在项目上 - $ typings install

   此外，如果您在防火墙后面，则需要将 .typingssrc 文件添加到项目根目录 - 项目安装的类型也需要离开防火墙，并且不能使用 npm 代理设置.

.typingssrc（文件名） { "proxy" : "http:// 添加你的代理服务器> /", “拒绝未授权”：假 }

Answer 2

使用npm i安装所有节点模块。为此，您需要在您的机器中安装nodejs。要检查您的机器中是否有节点，请使用node -v命令
