nestjs failed to run `bun build main.ts --compile` about bun HOT 3 OPEN

NestJS uses optional/peer dependencies for many modules, such as "@nestjs/microservices" and "class-validator" in your example.

To efficiently compile, bun needs to bundle all modules required by the code, even the ones you don't actually use. Have you tried installing all these libraries before compiling? It may fix the problem in the meantime. You could also set all these dependencies as "external" in your build step I guess.

However, it would be nice to allow compilation with these unknown modules.
Maybe with a flag like "--allow-missing-deps" or something?
And it would also be nice to document this behavior.

With v1.1.21 there's the new --packages=external flag. I didn't test it, but since the problem is due to optional dependencies, I bet it would solve the issue if it can be coupled with --compile.

Still, it would be nice to document that compilation with missing packages (add a warning about optional and peer dependencies, which are the most likely to trigger this) crashes. And that you have to either add the --packages=external flag, manually set the not-needed packages as externals, or install all of them.

I'm still rooting for an --allow-missing-deps flag of some sort, but that's probably just me.
