Problem npm run webpack (OS X)

Hi,

I tried the trouble shooting of running webpack but the issue still remains...

npm run webpack give me this error:

Sounds like my xs value is maybe not good looking but I double checked it..

Your development.json contains invalid json. Try this tool to determine the issue:
http://jsonlint.com/

Paste the contents of development.json and it will highlight the errors.

thanks for your quick answer!
problem solved!
Strange that Sublime Text did not highlight the mistake...
