Hi Fabio, I think the "rails new" command needs adjustment to use the args you specified, so you don't need to separately run `./bin/rails webpacker:install:react`

Just switch the app name and arg order like this:
rails new my_fancy_new_project --skip-action-mailer --skip-coffee --webpack=react

Lazy compile of webpack managed assets will happen auto-magically even without running webpack-dev-server. However, it is nice to have it for faster recompile and the live re-loading.
