lite-server 上的 npm 启动错误

Question

嗯，我现在从 Angular 2 开始，在第一个快速入门示例中，我遇到了“npm start”这个问题：

C:\nodejs\apps\angular2\01-cadastro-contatos>npm start

> angular-quickstart@1.0.0 start C:\nodejs\apps\angular2\01-cadastro-contatos
> tsc && concurrently "npm run tsc:w" "npm run lite"

 Error occured when executing command: npm run lite
 Error: spawn cmd.exe ENOENT

     at Process.ChildProcess._handle.onexit (internal/child_process.js:197:32)

我尝试了很多在这个网站上找到的东西，但都没有成功。 我在 Windows 10 x64 上...

你能帮帮我吗？

首先全局安装这些包，如下所示：

npm install -g concurrently
npm install -g lite-server
npm install -g typescript

接下来，删除 node_modules 文件夹并运行 npm install。 然后重新运行 npm start 。如果失败，请打开 package.json（在您的项目目录中）并更改

"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" "

到

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "

如果它以某种方式无法正确转义引号，发生这种情况，请将其更改为：

"start": "concurrently "npm run tsc:w" "npm run lite" "

然后再次重新运行 npm start。
