Quick summary

I recently cloned the wp-calypso repo and ensured that I followed the installation guide successfully. After installation, I tried to start the dev server with yarn start, the initial welcome page rendered but after webpack compilation, the CLI returned error messages and exited.

Steps to reproduce

1. clone the wp-calypso repo
2. run yarn to install dependencies
3. add 127.0.0.1 calypso.localhost to host file
4. run yarn start

What you expected to happen

After loading the initial welcome page: Welcome to Calypso!
Please wait until webpack has finished compiling and you see READY! in the server console. This page should then refresh automatically. If it hasn’t, hit Refresh.

In the meantime, try to follow all the emotions of the allmoji:

The browser should refresh when webpack is done bundling the app

What actually happened

I got the error messages in the terminal
