UIrouter compile error with Angular Ivy

Hi!

When using Angular Ivy compiler ng build --prod fails with

ERROR in src/app/app.module.ts(12,12): error TS-991010: Value at position 1 in the NgModule.importss of AppModule is not a reference: [object Object]

The ivy-ngcc compiler gives some warnings that could be related:

Compiling @uirouter/core : module as esm5 Warning: Unknown member type: "[key: string]: any; Compiling @uirouter/angular : module as esm5 Warning: Unknown member type: "[key: string]: any;

Here is a github repo to reproduce the issue uirouterivy and this commit is all that was done on top of a ng new uirouterivy . Steps to reproduce the issue:

git clone https://github.com/jr01/uirouterivy
cd uirouterivy
npm install
ng build --prod

It works fine w/o Angular Ivy:

git checkout 456833
ng build --prod

I’ve made more some progress

I’m not going to make any promises on timing of an ivy compatible release, but things are looking pretty good

git checkout ivy
yarn install
cd shinyivyapp
yarn install
npm run develop
