An unhandled exception occurred: Cannot find module 'webpack'

Hi!
When trying to build a web version on azure Pipelines, we're getting the following error:

An unhandled exception occurred: Cannot find module 'webpack'

The commands we're doing to build the angular app:

npm install -g @angular/cli 
npm install
npm run web:build

If we add npm install webpack webpack-cli --save-dev before we do the build, it succeeds to build, but the generated page is blank and in the console we see the following error:

polyfills.js:1 Uncaught ReferenceError: global is not defined

Are we doing something wrong?

@ItsMeRomian hi bro, Do you have found a solution? I got the same problem.

[ItsMeRomian]

@DwGoing ive removed all packages ive added on my own, grabbed the package.json from this repo and removed node_modules & package-lock.json and did a clean install. that fixed it.

I resolved problem by install the latest webpack.

npm install --save-dev webpack
