角度 2 - npm 错误

Question

我正在关注5 Min Quickstart - js - Angular 2 指南，但在调用“npm start”后遇到了一个奇怪的错误：

> angular2-quickstart@1.0.0 start C:\Users\stavalfi\Desktop\plunkerExample
> npm run lite


> angular2-quickstart@1.0.0 lite C:\Users\stavalfi\Desktop\plunkerExample
> lite-server

'lite-server' is not recognized as an internal or external command,
operable program or batch file.

更新：安装“npm install lite-server -g”时，出现以下错误：

Answer 1

错误代码ENOENT 表示“没有这样的文件或目录”。

您应该检查您是否有文件 C:\Users\stavalfi\package.json 存在并可供应用程序访问...您是否在正确的文件夹中执行命令？

Answer 2

您是否尝试过更新 npm？我在 5 分钟快速启动时遇到了一些其他问题，但在我更新 npm 后，我可以运行 npm start 而没有任何错误。
