     14% building modules 40/46 modules 6 active ...es\\@angular\\http\\@angular\\htt         


        

Answer 1

Do npm ls webpack

If you see two versions of webpack (under @angular/cli and the root node_modules), Then that is the problem. Delete/Rename the webpack under @angular/cli and in the .bin folder of @angular/cli.

Problem solved for me
