Cannot find module 'webpack' error in examples

I’m hitting the following issue when trying to run the examples which include webpack (in particular i’ve tried geojson and hello-world-webpack2)

npm run start
> @ start /home/david/git/deck.gl/examples/geojson
> webpack-dev-server --progress --hot --port 3030 --open

module.js:472
    throw err;
    ^

I’ve tried pretty much every suggestion from these two posts (uninstalling locally/globally, re-installing globally, installing with --save-local): https://stackoverflow.com/questions/29492240/error-cannot-find-module-webpack https://stackoverflow.com/questions/36393969/error-cannot-find-module-webpack

I’m running ubuntu 16.04 node v7.5.0 npm v4.1.2

@deejep That error normally means that you have another dev server running on that port

Try pkill -9 node or killall node in your console if you can’t find the offender.

@katzdave you need to install in the root directory as well. This is a known bug that we plan to address soon.
