Issue importing a package with module:true

[reconbot]

I went to import @sindresorhus/slugify which uses module:true in it's pacakge.json and it's .js files are esm. Here's a simple test case.

import slugify from '@sindresorhus/slugify'

console.log(slugify('I ♥ Dogs'))

And when I run it

$ npx ts-eager test.js
(node:66787) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

import slugify from '@sindresorhus/slugify'
^^^^^^

My settings for esbuild are able to bundle it however.

import { build } from 'esbuild'

build({
  entryPoints: ['test.js'],
  outfile: 'output.js',
  bundle: true,
  plugins: [],
  platform: 'node',
  minify: false,
  target: ['node14'],
})
