I have TypeScript 3.7 installed on a project, and I run tests with ava and ts-node. The issue I found is that compilation works as expected, but tests fail because ts-node doesn't recognize the syntax for nullish coalescence and optional chaining.

So if I have:

foobar?.foo?.bar ?? "default value"

I get errors all over the place. Isn't ts-node using the local typescript package to do compilation?
