What can be wrong here?

I don`t know what should I write yet to not make it look like this post is mostly code. I did add many details including my environment versions.

Like @circleofconfusion, I am effectively seeing this on my CI (and also a docker container which does some things to my node_modules folder that are likely also to happen on a CI).

I found the argument --preserveSymlinks when passed to ng test (that is where I am seeing the error) will break the recursion (fix) resolving the module I was having an error with.

You will find this argument in https://angular.io/cli/build and you can edit your angular.json to set the property so you don't need to specify it on the commandline. You will need to add it to the options block in each of the problematic builders (likely in any of the builders that start with "@angular-devkit/build-angular") . This will tell angular to not resolve the symlinks to their actual path, and fixes the issue I have (my node_modules is actually symlinked to a shared location)

Hope this helps!
