trying to install from the extension manager gives this result:

this should fix it:
https://katalon-inc.my.site.com/katalonhelpcenter/s/article/How-to-fix-Git-Clone-Filename-too-long-Error-in-Windows
So I as a user did:

1. Git Global Level

Please follow the steps below to fix "Filename is too long" in Git.

Update to the newest version of git. If you have already upgraded, skip this step.

Navigate to your project folder

Open the Git Bash and run it as an administrator

To enable long paths in Git Bash, use "git config --system core.longpaths true"

Now clone the project with longer filenames that should no longer generate a problem. This solution mostly works for users to fix the issue. It is applicable to all repositories that will be cloned for future projects.

I have the same problem. I tried the fix above and it didn't work.

Same, it's the only one I consistently have issues with

The problem seems to originate from the installation of mediapipe.Need python 3.7-11

[GoooIce]

if you want install this with python3.12 for now [2024.4.10]. just try:

1. download mediapipe-0.10.11-cp311-cp311-win_amd64.whl from pypi site
2. rename it to mediapipe-0.10.11-cp312-cp312-win_amd64.whl
3. pip install
4. edit custom_nodes\ComfyUI-Inference-Core-Nodes\pyproject.toml line 9: requires-python = ">=3.10,<=3.13"
5. run python install.py

enjoy...

If I just re-name it like you suggest, I get an error that it's not a supported wheel

PS D:\Documents\stable-diffusion\stableswarmui\StableSwarmUI\dlbackend\comfy\ComfyUI> ..\python_embeded\python.exe -m pip install .\mediapipe-0.10.11-cp312-cp312-win_amd64.whl
ERROR: mediapipe-0.10.11-cp312-cp312-win_amd64.whl is not a supported wheel on this platform.

Managed to fix this on my end on a portable Windows install, it seems like filename too long error allowed to set up a broken dependency chain which had to be manually re-installed. Setting "git config --system core.longpaths true" allowed an install to complete but did not fix the root issue on Windows, as Windows appends file locations that exceed the default limit with "\\?\" which then breaks some of the dependency references that are set up with an absolute path that does not include the prefix. This then allowed a broken install of dependencies that created only the .dist-info files and not the python files themselves for some of the dependencies, and for others broke references made within the dependencies themselves.

Additionally, Im using the portable version of comfyUI, and the pip dependencies seem to install to a default python env in the root drive under X:\python\Lib\site-packages and not ComfyUI_windows_portable\python_embeded\Lib\site-packages.

The fix that worked for me was

1. shortening the amount of characters in the filepath (simply renaming the top level folder from the default wordy folder name to simply "comfyUI", it helped that my comfyUI install is in a folder in the top level of a drive)
2. uninstalling and re-installing the dependencies;

• In command prompt, navigate to the ComfyUI\ComfyUI_windows_portable\ComfyUI\custom_nodes\ComfyUI-Inference-Core-Nodes> folder
• pip uninstall -y inference_core_nodes
• pip install . -vvv
• this will show you all the requirements that have been installed, dont be fooled by "requirement already met" some of these will likely be broken installs
• pip uninstall again
• pip uninstall all of the installed requirements listed in the previous step
• do another fresh install using pip install . -vvv
• copy all of the files under X:\python\lib\site-packages into ComfyUI_windows_portable\python_embeded\Lib\site-packages

As long as the filepaths are still not too long, this should correct the python dependency chain that creates this error.

I have the same problem too on a windows 11 machine.

I tried the enable long paths fix but it didn't work for me.
