Issue details

Hello! I'm using Pulumi Service via Pulumi GitHub Actions and it looks like it uses an outdated version of TypeScript, because it can't recognize some compiler directives that I use. Effectively this prevents me from extending reusable TypeScript configurations and I have to manually copy the configuration and downgrade it by removing/changing the problematic options.

It would be much better if Pulumi would respect and use the TypeScript compiler listed as a project dependency. E.g.: npx tsc (node_modules/typescript/bin/tsc).

Affected area/feature

I believe it is related to the Pulumi Service product.

Hi @slavafomin I'm not sure I understand. It sounds like the issue is that the Pulumi CLI uses a pinned version of TypeScript that's incompatable with your project, not that this action's TypeScript build is incompatible.

It sounds like you're hitting this issue here.
If that's the case, I'll just briefly reiterate what makes that issue difficult to solve: moving TypeScript to a peer dependency (thus allowing you to provide your own version in your package.json) is a breaking change. We might be able to work around that with a dynamic import, but we need a brief spike to figure that out.

This package uses TypesScript v4.1.3. Is your project using features from a newer release?
The Pulumi NodeJS runtime bundles v3.8 IIRC.

Hi @slavafomin, happy New Year. I just wanted to follow up on this issue. Have you had a chance to confirm you're encountering pulumi/pulumi#8177?
