Cannot npm run server without first installing es-to-primitive

[FindingNamo]

Looks like strictly following the readme.md leads to a failure on launching the server.

$ npm run server

dim@4.29.0 server xxxxxxx\repos\dim
webpack-dev-server --config ./config/webpack.js --env=dev

module.js:538
throw err;
^

Error: Cannot find module 'es-to-primitive/es6'

Need to also install es-to-primitive

Probably can be solved by adding to package.json?

This ended up being specifically a git bash issue on Windows.

It looks like, even if run as admin, git bash is not going to npm install correctly all the modules required leading to several modules missing, specifically es-to-primitive and is-regex.

Using any other shell seems to work as intended :(.

Thank you to @48klocs who helped investigate.

It'd be nice to update the README for windows users.
