Watcher cannot resolve 'memize'

[emfluenceindia]

I am trying to build a custom block which is supposed to place it in the editor with 2 columns by default and then from Inspector control I can increase it up to 6 columns.

I am following https://github.com/WordPress/gutenberg/blob/master/packages/block-library/src/columns/index.js

The watcher is unable to resolved, i.e. memize
The error message is Module not found: Can't resolve 'memize' ...

import classnames from 'classnames';
import memoize from 'memize';

I went through #6707 but did not understand much of it.

I am a beginner to Gutenberg development. So don't know what I am doing wrong. I did skip some part of the code from the above URL as looked like I don't nee them in my custom block.

I have uploaded my code at https://gist.github.com/emfluenceindia/71846f7c76b19f8a974a0c3e0a30d4df

How can I fix this? :(

Hi there!

If you're building your JS files, make sure to install memize as an npm dependency (add to package.json + npm install)
