问题:

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

It's been days now please help me

回答1:

npm install events

install events using npm.

回答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...
