webpack: bundle is now VALID.

This is a blocker for using the latest, current solution is to use version 7.

Current Behavior

Cannot build project

Expected Behavior

Should work on older Typescript versions as Angular 4 has not even upgraded to 2.4.

Steps to Reproduce

import * as ScrollBar from 'smooth-scrollbar' with Typescript version below 2.4

😧 TypeScript 2.4 has been released for months but they do not support it yet??? That is too bad since I am a radical who is always excited about new features.

This is really a big blocker for me. I might not fix this issue until they roll out new release with latest TypeScript support.

Oh sorry. Hit the close button by accident 😅

It seems angular-cli has already supported TypeScript 2.4: angular/angular-cli#7578

So if you want to install ts 2.4 in your new project, the CLI itself won't stop you.

angular-cli@1.5 supports ts 2.4 by default.
