Cannot resolve @angular/http in node_modules\@angular\platform-server\bundles in angular 5 aspnet prerendering

Question

I am using Angular 5 with spatemplates in ASPNET Core. Once I updated the packages and modified the webpack.config.js . I am trying to run --

webpack --config webpack.config.js 

to generate the main-server.js and vendor.js. However I am getting the error below. Why is this being thrown?

 ERROR in ./node_modules/@angular/platform-server/bundles/platform-server.umd.js
    Module not found: Error: Can't resolve '@angular/http' in 'D:\Neudesic\eMedHat\eMedHat Web\dev\Source\eMedHat\eMedHat.SurveyPortal\node_modules\@angular\platform-server\bundles'
     @ ./node_modules/@angular/platform-server/bundles/platform-server.umd.js 7:246-270
     @ ./ClientApp/boot.server.ts

The issue was it was using npm shrinkwrap . so even if I updated the package.json. I had to still update the shrinkwrap . Else it won't update the packages . The shrinkwrap.json locks down the npm package versions
