【问题描述】：

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：

MSBUILD : error MSB3428: Could not load the Visual C++ component "VCBuild.exe". To fix this, 1) install the .NET Framework 2.0

【参考方案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？

【讨论】：

包没有放在正确的位置。但现在我得到了新的错误。任何额外的帮助都会得到祝福！

我会说你的精简服务器没有安装在全球范围内。尝试使用-g 选项：npm install lite-server -g

这样做并得到了一些奇怪的错误。我确实有 VS 2015，我认为它带有 C++ 编译器。

【参考方案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。
