Failed at start script

When I try npm start I get the following error:

npm ERR! Windows_NT 6.1.7601
npm ERR! argv "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" "start"

Any hint?

@Kohze - do you have anything running on port 8081? Can you try:

PORT=9090 node dev-server

Didn't solve it, the message it returns is that it does not know how to interpret "PORT" . Other than that the log is:

Update: Solved the Issue. Apparently it was OS specific. For everyone using a windows machine the line

"start": "PORT=8081 node dev-server.js"

needs to be replaced with

"start": "set PORT=8081 && node dev-server.js"

Thank you, @Kohze for diving deeper. I pushed a Windows starter script. Hopefully it would help for the Windows platform users. Please let me know if it doesn't work.
