Module not found (webpack)/hot/emitter @angular-devkit/build-angular after ionic serve - Ionic 4

Question

Stack:

node v10.15.1
ionic 4.10.1

When I run ionic serve I get:

ERROR in (webpack)/hot/emitter.js [ng] Module not found: Error: Can't resolve 'events' in '/zazou/node_modules/@angular-devkit/build-angular/node_modules/webpack/hot'

Failed to compile.

Couldn't find an answer for this.

I tried to:

update @angular-devkit/build-angular
npm install webpack-hot-dev-clients
npm install -g webpack and npm install -g webpack-dev-server as suggested here
npm link wepack
I also tried to update my angular CLI

Install events using npm.

npm install events

Or to save other people (e.g. repository users), run:

npm install events --save --dev

Your comment helped us on an Angular 7 project. Though events weren't being used anywhere, we added as devDependencies since it wasn't running without it. Thanks!

Why is this not installed with webpack if it's required?

(same pb with angular 7, using angular/cli)

I don't have THE solution (as I don't really understand the issue), but after a lot of tries, it worked, so let me describe what I did, maybe it'll help you...

swicth to node 9.5.0 (used n to do it)
switching to npm 5.6.0
remove global webpackage (I installed it for a try to solve version..)

npm uninstall webpack -g
rm -rf node_modules
npm install
then an issue with rxjs-compat, so I installed the version 6.4.0 for rxjs and rxjs/compat

Then it worked... Maybe executing one of these steps will help you...

I also encountered this (when updating to Angular 11). To fix I had to:

rm -rf node_modules
rm package-lock.json
