npm ERR node V, npm ERR npm V running an android app with ionic on Windows

I have a problem with running a program via ionic. I installed everything that is needed and tried to emulate an android test app, and it worked without any problems But if I try to start the program of my colleague:

npm ERR! Windows_NT 10.0.15063
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "run" "ionic:build" "--"
npm ERR! node v7.10.0
npm ERR! npm  v4.2.0
npm ERR! code ELIFECYCLE
npm ERR! errno 1

These errors occur and we're confused what that means. He developed this app on a Linux machine, and if he's starting the app on his machine, it works. I'm using a Windows machine. Could that be something, that is responsible for our problem? We both have the same node/npm version. I use the "ionic run android" command, to start the app.

And btw. the full error logs, if it helps:
