install using yarn failed

See original GitHub issue

I use jhipster angular 4 generator and add sweetalert angular dependency

yarn add sweetalert2 @toverux/ngx-sweetalert2

And I got this error on running using webpack dev server

Uncaught Error: Unexpected value '[object Object]' imported by the module 'MyModule'. Please add a @NgModule annotation.

Thanks, I understand what the problem is. The issue is on my side indeed, expect a fix in the next few hours. In the meantime, and if I’m right, I think that you may be able to workaround it by deleting node_modules and yarn.lock and re-run yarn install. That should dedupe the Angular dependencies, which is what causes the problem here.

Sorry for the inconvenience!
