installing with latest update of comfyui error (IMPORT FAILED) ComfyUI-LTXVideo

[MoreColors123]

I tried it all, easynodes still gives me errors. I saw that there is now a new command for installing packages for portable Comfy, but i honestly don't know where to execute it. I tried it inside the customnode folder, the python_embed ... Please help.

Run command with administrator privileges

Ok solution is to install via comfy manager. Didn't think of that. Maybe the code was updated too, I'm not sure. Yesterday it didn't work after trying, but I always just git cloned. Now i can finally play around with the provided workflows.

Here's your response formatted for GitHub:

I am experiencing the same issue. I installed the module using the Manager, but it doesn't work.

I've tried the following steps:

• Deleted and reinstalled the module.
• Updated all dependencies.
• Manually installed the requirements.txt file.

Despite this, I encounter an error when installing the ltx_video module. Upon starting ComfyUI, I get the following error:

Traceback (most recent call last):

for me this happened due to the removal of the long-deprecated pkgutil.ImpImporter class, the pip command was not working for python 3.12

i installed python 3.11 and it was working after that

if nothing works, update your git on your pc. theres a git version that has a rollbacked LFS handling fix that causes issues when its trying to pull the additional big LFS data from the repo.

Here is what solved this problem for me. (on a Mac) I wasn't able to either install this node via the manager nor install it via terminal with the "git clone https://github.com/Lightricks/ComfyUI-LTXVideo.git". When trying to install it via git clone I always got the message that the node was installed successfully but couldn't check out. So the node wasn't installed completely and wouldn't work. The issue with the checkout step was due to Git LFS (Large File Storage). This means that the repository I was trying to clone uses Git LFS to manage large files, and my local Git environment didn't Git LFS installed. The solution (I assume you have Homebrew installed):

Install Git LFS: brew install git-lfs Initialize it: git lfs install

After that I cloned the repository once again (I had to delete the already existing folder comfyui-ltxvideo for it to work) and the clone was complete with all files, so that I could rum pip3 install -r requirements.txt and use this node after that.
