Hi @Sdreamtale . I got same issue and solve it follow these steps:

git pull origin master

[ltdrdata]

It seems that your ComfyUI is in the abnormal state. Goto the ComfyUI dir and execute

git branch -al

What is displayed?

[imnoop]

I have the same issue as well, when I do 'git branch -al' I get:

update: Apparently I made some changes to requirements.txt (to update just some of the python packages, without messing with pytorch as I have nightly installed), deleted requirements.txt then "git pull origin master" worked, thanks.

me too, can't update

I'll need to provide a more detailed failure report regarding the modified file situation.

[master-key-g]

It seems it comes from this file for what ever reason requirements.txt. I checked my file is the same as the on on the github

[AntonZhygalov]

Had same issue fixed it using: git fetch origin

[oakis]

I was somehow checked out to a version branch so i just stashed the changes to be safe and checked out master. Then i ran update and it was working fine.

[rzgarespo]

cd comfyui-directory git reset --hard git pull origin master pip install -r requirements.txt
