I'm having the same problem with similar libraries (like web3-eth-accounts). But I think that the problem comes from Angular upgrade and the webpack configuration.

Related issue here:
#1555

Workarounds suggested:

• downgrade to Angular 5
• try upgrading NodeJS version which includes crypto
• download the build files from the releases page, copy the source to app/src and include it on scripts property of the angular.json config

I tried these, and they didn't work for me! From what I understand it's an issue with the typings file. Or a dependency.

My workaround was to downgrade to an older version of web3:
npm install [email protected]

Another workaround is the suggested here: angular/angular-cli#1548 (comment)
It replaces the webpack config of @angular/cli

The solution with the patch worked for me!

node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js
node: {crypto: true, stream: true}
