Doesn't find libraries when using ES modules

[codetheweb]

Issue description

What the title says. When using ES modules, this package can't seem to find the supporting libraries.

i.e.

Discord.js client is ready!
--------------------------------------------------
Core Dependencies
- @discordjs/voice: 0.7.2
- prism-media: not found

Opus Libraries
- @discordjs/opus: not found
- opusscript: not found

Encryption Libraries
- sodium: not found
- libsodium-wrappers: not found
- tweetnacl: not found

FFmpeg
- version: 4.4
- libopus: yes
--------------------------------------------------

even though @discordjs/opus is installed.

See repro.

Code sample

No response

@discordjs/voice version

Priority this issue should have

Medium (should be fixed soon)

This is related to this issue with esbuild evanw/esbuild#946

Affected files are:
https://github.com/discordjs/voice/blob/main/src/util/generateDependencyReport.ts
https://github.com/discordjs/voice/blob/main/src/util/Secretbox.ts
These files use require which is not defined in es module scope. But esbuild should have created the require function in this case.

There is a workaround described in the esbuild issue but maybe we should consider migrating to dynamic import syntax or reading and parsing json files manually

Same here on Linux (Debian 10 Buster).

Since it seems several other people are having this issue as well, would it be possible to add a workaround for now and then perhaps look at other options later (I assume those would take longer than adding a few config lines)?

Is this a workaround in your build or a workaround we're expected to run in our environment?

[RealAlphabet]

I found a rather elegant solution to avoid modifying all your code to CJS.
This way NodeJS will load the CJS version of @discordjs/voice instead of ESM.

import { createRequire } from "module";

const {
    joinVoiceChannel,
    createAudioPlayer,
    createAudioResource,
    entersState,
    VoiceConnectionStatus,
    NoSubscriberBehavior,
} = createRequire(import.meta.url)("@discordjs/voice");

Let me reopen this issue to notify of a strange behavior that may occur when using createRequire.

Just to be sure, this should remain a temporary solution until the problem is fixed on esbuild.
Otherwise we should find another solution to load the dependencies.
