This fix still works tho: #1110 (comment)

[ghost]

Temporary fixed solution is downgrading ytdl-core version forked by @GreepTheSheep:

npm i ytdl-core@https://github.com/GreepTheSheep/node-ytdl-core

For mine, this fixed the "Invalid regular expression: missing / "

[Roninanu777]

For me the patch by @khlevon worked

"ytdl-core": "https://github.com:khlevon/node-ytdl-core.git#v4.11.4-patch.2"

[azickri]

For me the patch by @khlevon worked

"ytdl-core": "https://github.com:khlevon/node-ytdl-core.git#v4.11.4-patch.2"

How about speed download?
Its throttle?

[milanbabiclibrafire]

This worked for me:
Using last ytdl version (same download speed)

1. delete node_module, package-lock.json
2. "ytdl-core": "github:milanbabiclibrafire/node-ytdl-core"
3. npm i

If you don't want to use a fork, you can also use a patch.

I use the patch-package to create a patch for a particular module

Example: https://github.com/Mittelbots/Mittelbot/blob/ae1ee59206ec51b15e51d4573c6aabec13bb3d53/patches/ytdl-core%2B4.11.4.patch

[Shajeel-Afzal]

"ytdl-core": "https://github.com:khlevon/node-ytdl-core.git#v4.11.4-patch.2"

It works perfectly on localhost however I am not able to deploy to Firebase Functions after adding this to package.json.
Any solution?

@Mittelblut9 in your patch one important line is removed, here is a correct one https://gist.github.com/talyuk/6f197e6a58b7b8107a7c2d7f442b97ae

Fixed 😅🫡

I recommend using @distubejs fork since it is active, has fast bug fixes, and has better performance with undici.
npm i @distube/ytdl-core

If you don't want to change your package name, you can overwrite the original package with this command.
npm i ytdl-core@npm:@distube/ytdl-core

It should work better since #1217 patch is copied from this fork

[Shajeel-Afzal]

npm i ytdl-core@npm:@distubejs/ytdl-core

It says 404 not found!

[fpsone]

npm i ytdl-core@npm:@distubejs/ytdl-core

It says 404 not found!

Sorry, their package org doesn't have js suffix, it should be @distube/ytdl-core. Edited

Seems like the issue is fixed, at least "ytdl-core": "4.11.5" is working for me

Downgrade should work but the download speed is throttled and extremely slow.
You can use "ytdl-core": "npm:@distube/ytdl-core@latest" for better performance.

"ytdl-core": "4.11.5" is not working again

Changed to "ytdl-core": "npm:@distube/ytdl-core@latest" And it fails randomly with an error:

Yeah, there is no ffmpeg/ffprobe inside it this package

But this is my internal logic to use downloaded files. And seems like "ytdl-core": "npm:@distube/ytdl-core@latest" is randomly downloading empty files

I never found that issue
