I\'m building an Angular 6 app, but every time I want to serve to localhost, I get these errors:

ERROR in ./node_modules/aws-sign2/index.js
Module not found         


        

Answer 1

You are using the latest version of Angular CLI. Some npm packages are no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.

To fix your issue with crypto, stream libs, go to,

node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/browser.js

file and do the following change,

`node: {crypto: true, stream: true}`
