Not installing nodes

[Lucavdg]

I don't know why, but for some reason these nodes do not get downloaded when I install the node package. I've tried eveverything from reinstalling comfyui, downloading from the manager, from github and manually. Nothing seems to solve this issue?

Hi @Lucavdg ! Thank you for reporting this issue.
Could you please let me know what OS/ComfyUI install method you are using? (Windows/Linux, git clone/portable/desktop).

I would also encourage you to try installing the latest version of the node pack because I think I may have solved your issue already:
version = "0.1.21"

Same problem for me. I have files installed, but no nodes on Comfyui. I use Linux fedora 43. Tried installing via manager (nightly) and using linux konsole. In manager it shows node pack installed, but no nodes appear in search.

Hi @werbals! Thanks for reporting the issue :) I would recommend installing the numbered version because of ComfyUI-Manager quirks. At any rate, could you send me the install log? :) I really want to make this work!

@PozzettiAndrea issue might be my os, comfy setup related. I am running Linux Fedora 43 and comfyui is installed in docker container. After seeing the log, something might be related to folder permissions. This happens not with just your package. Also have problems with updating comfyui manager. Trying to solve using AI help, but so far nothing helped.

I'm getting a different issue related to a venv file missing. Full installation log follow with redactions in square brackets:
