angulartics2: `ERROR in src/app/app.module.ts(9,46): error TS2307: Cannot find module 'angulartics2/routerlessmodule'`

• I’m submitting a … [x] bug report [ ] feature request [ ] question about the decisions made in the repository

• What is the current behavior?

When using https://github.com/angulartics/angulartics2#using-without-a-router in a project I get on ng serve:

webpack: Compiling...

webpack: Compiled successfully.

Interestingly enough this still compiles and can normally be run.

• What is the expected behavior?

No error message, still working.
