The issue is /node_modules/esvu/dist/src/index.js

'use strict';

const fs = require('fs');
const path = require('path');

const engines = {};
const enginesByName = {};
fs.readdirSync(path.join(__dirname, 'engines'))
  .forEach((f) => {
    if (!f.endsWith('.js')) {
      return;
    }
    const e = require(`./engines/${f}`);
    engines[e.config.id] = e;
    enginesByName[e.config.name.toLowerCase()] = e;
  });

becomes

// node_modules/esvu/src/index.js
var require_src2 = __commonJS((exports, module) => {
  function getInstaller(name) {
    name = name.toLowerCase();
    if (engines[name]) {
      return engines[name];
    }
    if (enginesByName[name]) {
      return enginesByName[name];
    }
    return;
  }
  var __dirname = "/home/user/node_modules/esvu/src";
  var fs = import.meta.require("fs");
  var path = import.meta.require("path");
  var engines = {};
  var enginesByName = {};
  fs.readdirSync(path.join(__dirname, "engines")).forEach((f) => {
    if (!f.endsWith(".js")) {
      return;
    }
    const e = import.meta.require(`./engines/${f}`);
    engines[e.config.id] = e;
    enginesByName[e.config.name.toLowerCase()] = e;
  });
  exports.getInstaller = getInstaller;
  exports.engines = engines;
});

The bundle is looking for ./engines/${f} in the current directory. The path should be ${__dirname}/engines/${f}.

Adding the __dirname manually to the bundle works.

Looks like the larger issue is the result of bun build --compile still depends on the source files after executable compilation #14676.
