postinstall scripts in monorepos aren't run if there's errors with the installation

[Hebilicious]

What version of Bun is running?

v0.8.1

What platform is your computer?

Cloudflare pages v2 (I haven't been able to reproduce the bug locally)

What steps can reproduce the bug?

In a monorepo with the following structure :

• packages/foo/package.json
• package.json

The postinstall script in foo/package.json script doesn't run when running bun i.
I tried with { "trustedDependencies": ["foo"] } in the root package.json without success.

I suspect the reason is that I'm getting this error while installing dependencies. This error doesn't seem very important and I'm able to manually run the postinstall scripts later.

00:16:26.655 | 1618 packages installed [16.94s]
-- | --
00:16:26.655 | Failed to install 2 packages
00:16:26.656 | error: PathAlreadyExists installing strip-ansi
00:16:26.656 | error: PathAlreadyExists installing string-width

What is the expected behavior?

I would expect the postinstall scripts to run (They run locally on my machine Darwin 22.6.0 arm64 arm)
Additionally if the error is not critical, maybe the postinstall scripts should run before the error, and we could have a way to ignore/silence it or it should be a warning instead?

What do you see instead?

I have the same issue.

I'm also having this issue in Github Actions, but not locally (Apple Silicon). My workaround is this at the moment:

- uses: oven-sh/setup-bun@v1

- name: Install dependencies
   run: bun install --frozen-lockfile && bun run postinstall

I got this issue with this repo: https://github.com/SaphireBot/Bot

Please fix this!

not only post install but any hook. My repo is a monorepo that defines the prepare script for the packages to be built and those don't run after the error.
