issues with latest version. staying on 0.2.7

[bobOnGitHub]

This is a really useful module which I want to keep using.

I was using it a lot but haven't been doing much node in 2/3 yrs. Version 0.2.7 ( 20K downloads in last wk ) still works, fairly intuitively, with no problems, as documented.

Install latest (2.1.1) and I'm looking at problems for over an hour now. Eg.

The following options are supported:
  -u, --username <ARG1>         db username
  -p, --password <ARG1>         db password

Why the error message when neither is "required" ?

as expected. try something else...

[bob@wsa test]$ cat main.js
import { getopt } from 'stdio';

const options = getopt({

    password: {key: 'p', args:1, description: 'db password',required:false}

Still error.
