Describe the bug
I had been working on a NS/Angular project for a month or so. The code base isn't mine and is a bit old, but I'm doing some updates/bug fixes/etc. I was working just fine, when I noticed issues testing on a new phone. I checked to see if my CLI was out of date, it was, so I updated to 5.4.2.

At that point, things went to heck in a handbasket. The CLI prompted me to update to webpack usage, I said yes, and nothing worked right.

I reverted, tried again, and told it no. I've also run tns update.

Now I get the following output when doing tns build android,

To Reproduce
Not sure what to suggest here. As I said, it was an absolutely working project with an earlier version of the CLI.

Expected behavior
For it to build. :)

Comece reproduzindo tns build android com as versões listadas de CLI, runtime, plugin e TypeScript. Inspecione os imports curtos em app/utils/offline-util.ts, app/utils/tapsound-util.ts, app/utils/trackKeyboard-util.ts, app/vendor.ts e app/vendor-platform.android.ts, juntamente com os erros reportados de tns-core-modules. Considera-se concluído quando o projeto existente for compilado com sucesso.
