npm install error on webpack version dependency

[goldensunliu]

I am getting this error when installing:
npm ERR! notarget No compatible version found: webpack@'>=1.2.0 <1.3.0'

I suspect it is due to this line in package.json:"webpack": "1.2.x",

Changed "webpack"and webpack-dev-server from 1.2.x to 1.3.x and it worked.
