Babel/browserify throws "Error while parsing JSON - Unexpected token o"

Weird error when attempting to use browserify and babel:

./node_modules/.bin/browserify app/index.js -o bundle.js -t [ babelify --presets [ es2015 react ] ]

gives:

SyntaxError: /.../package.json: Error while parsing JSON - Unexpected token o in JSON at position 1 while parsing file: /.../index.js

I have the proper presets installed for es2015 and react, but I have no idea why it's throwing up this error. The weird thing is, this command is working on my production server...

Any ideas?

This is the package.json parsing error, Check whether there is an package.json file at my user directory, if exist, delete it.
