Well, i'm starting with Angular 2 right now, and in the first QuickStart example, i'm facing this issue with "npm start":

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 exports._errnoException (util.js:1020:11)
     at Process.ChildProcess._handle.onexit (internal/child_process.js:197:32)

I tried many things found on this site, but without success. I'm on Windows 10 x64...

Can you help me?

Install these packages globally first, like so: 

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

Next, delete the node_modules folder and run npm install. Re-run npm start then. If that fails, open package.json (in your project dir) and change 

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

to

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

In case it somehow fails to escape the quotation marks properly, which happens, change it to: 

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

And then re-run npm start again.

    Just a note: If you're going to put `concurrently` `lite-server` and `typescript` in npm script, you don't need to install them globally. Local modules will be used. – AdityaParab Oct 16 '17 at 11:46
  • True, but I added it in just in case as he's beginning to develop with Ang and might need those packages throughout more projects. Voted up. – Milan Velebit Oct 16 '17 at 11:50
  • Edited the answer, try again. If all that fails, reinstall node completely and re-do it. It's a bug either due to the typescript compiler or Node itself. – Milan Velebit Oct 16 '17 at 12:09
