Excellent and succinct repro, thanks ❤️ I'll work on a fix tomorrow - the issue seems to be that an assumption made that a import def from "foo" alias target always has a parent symbol isn't _quite_ true when esModuleInterop is on (as the target may end up being the module itself!)

I just tried with the latest build, I am still getting this error.

ajayvikas on 18 Oct 2019

"latest build" being @next? Or the beta? The fix is still only in @next and hasn't shipped in a tagged release yet.

weswigham on 19 Oct 2019

Sorry I was not very specific. I took the @next. Precise build number is 3.7.0-dev.20191018.

ajayvikas on 19 Oct 2019

Same as @ppn2, but downgrading to 3.7.0-dev.20191017 let me compile without this error.

I got this today when I updated 4.0.1 to 4.1.2 on a big project(has esModuleInterop enabled):

I should probably open this as a new ticket right @weswigham ?
