however it is the

pulumi-language-nodejs

process that locks up.

Looks like another annoyance with the customised runtime that the pulumi program runs in. When add a package dependency with file path:

file:../../

to the package.json, pulumi crashes (even though the module of that package is not imported in the index.js). Removing it again, fixes it (however there seems to be a cache issue too, in which it intermittently doesn't fix it). Running the

index.js

with node directly causes no problems either way.

I'm still not able to reproduce it in isolation. It does seem to matter what kind of package it refers to.

So now I have two identical projects, with a barebones package in root directory that only contains a package.json, with name, version and description and a nested subdirectory that contains an empty

index.js

as a pulumi program with a

devDependency

that points to

file:../..

, the package in the parent directory (yes, 2 levels up). One of these projects works and the other does not (it freezes). The one that doesn't work used to be more complex, before i started removing stuff from it to isolate the problem. I suspect its a cache issue, but I cannot figure out where it comes from.
