Error building with calypso build

[renatho]

Steps to reproduce

1. Setup a basic project with only an index.js
2. My package.json

   {
   "name": "test",
   "version": "1.0.0",
   "description": "",
   "main": "index.js",
   "scripts": {
   "test": "echo \"Error: no test specified\" && exit 1",
   "build": "calypso-build ./index.js"
   },
   "author": "",
   "license": "ISC",
   "devDependencies": {
   "@automattic/calypso-build": "^6.1.0"
   }
   }

3. Run npm run build

What I expected

To build correctly.

What happened instead

Receiving this error:

Context / Source

I was creating a new project using the calypso-build to build. And while running I was getting the error.

I also tested in some projects (Sensei) where we are using it. It's working, but when removing the package-lock.json the error appears too.

Here are some discussions with possible workarounds: https://stackoverflow.com/questions/60780664/could-not-find-plugin-proposal-numeric-separator
