zeromq + vite + electron also fails (MAIN PROCESS! NOT RENDERER)

[devzzzero]

Describe the bug A clear and concise description of what the bug is.

This is similar to #676
I've given up trying to get zeromq working on the renderer side and instead using ipc to hack up the required communication hooks to the renderer from the main process, and managed to get the app limping along and running (on webpack).
However, I ran into what seems to be another blocker. When I package up the app, the resulting app dies because it's unable to find zeromq. Please see webpack/webpack#18995 (reply in thread)

I then tried to get electron+vite+react + zeromq to work, and ran into a strangely similar issue.

Reproducing If possible, provide a list of commands or a code sample that
reproduces the bug that you are observing. Otherwise please describe as much as
possible in which circumstances the bug can be observed.

I followed the instructions on https://electron-vite.github.io/guide/getting-started.html
to get a electron+vite+react.

I then added zeromq and verified that the tests do run using tsx
But ran into this one:

Uncaught Exception:

Over on the webpack side, I managed to get past this issue (at least for the "run") by having zeromq listed as an external dependency.
but the packaged app fails.

On vite (this issue), I'm unable to get the app to run at all

Tested on

• OS: [e.g. Ubuntu 18.04, Windows 10]
• opensuse 15.5
• ZeroMQ.js version: [e.g. 5.1.0, 6.0.0-beta.2]
• 6.2.0

Hi. So it's not enough to mark zeromq as external. Both webpack and vite fail the same way with the BUILT app (i.e. the result of npm run build)

FYI: this is in the main process in electron. NOT THE RENDERER.
