Unable to start formeo - Githubissues

Hi,

I am trying to install and run formeo using the instructions under Contributing:

git clone https://github.com/Draggable/formeo.git
cd formeo
npm install
npm start

However, everytime I run npm start, it shows an error as per below:

npm start                         

> formeo@1.0.10 start /Volumes/LaCie/Arsyad/websites/formeo
> npm-run-all build:icons start:demo

> babel-node ./tools/generate-sprite

> formeo@1.0.10 start:demo /Volumes/LaCie/Arsyad/websites/formeo
> cross-env NODE_ENV=development webpack-dev-server --mode development --open --config tools/webpack.config --copy

        this.options.chunkFilename = filename.replace(/(^|\/)([^/]*(?:\?|$))/, '$1[id].$2');
                                              ^

I also tried running using yarn install but received another error:

yarn install
yarn install v1.3.2

Is there any steps I am missing? I have already installed webpack but it doesn't work:

npm install --save-dev webpack
npm install --save-dev webpack-cli
