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

Answer 1

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! – Contribution

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

Answer 2

(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...

Answer 3

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

rm -rf node_modules
rm package-lock.json
