Angular 6 many Can't resolve errors (crypto, fs, http, https, net, path, stream, tls, zlib)

Question

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 have to find the node packages added as dependencies which is causing this issue. Open package-lock.json, search for crypto can find the chain of dependencies leading to the package name included in dependencies section of package.json. In my case, most of these libraries were brought in with npm package 'request'.
