Webpack SyntaxError: Unexpected token =>

Question

I just moved my project from one machine to another, and when I run webpack --watch I get the following error:

C:\Users\joe_coolish\AppData\Roaming\npm\node_modules\webpack\bin\webpack.js:186
                outputOptions.children = options.map(o => o.stats);
                                                       ^^
SyntaxError: Unexpected token =>

    at Function.Module.runMain (module.js:501:10)
    at startup (node.js:129:16)

The exact same setup on my other computer transpiles without any issue. What could cause this?

My Webpack version is [email protected]

I've run npm install in my app directory. My packages.json is:

Well, I feel dumb...

I just did a node --version and it came out with the value v0.12.2

Just installed v7.5.0 and everything works just fine now.
