How to Upgrade ComfyUI

This guide will walk you through upgrading ComfyUI. The process varies based on how ComfyUI was installed, so not all upgrade methods may be covered here.

We will discuss the following methods for upgrading ComfyUI:

1. Upgrading ComfyUI for Windows users with the official portable version.
2. Upgrading ComfyUI for users who installed it manually using Git.
3. Upgrading ComfyUI for users using aaaki ComfyUI Launcher.

Please note that methods 1 and 2 require access to GitHub. If you're in a region where GitHub access is restricted, you might need to set up a network proxy. For Windows users, using 秋叶启动器 is generally recommended for easier management.

Upgrading ComfyUI for Windows Users with the Official Portable Version

1. Navigate to the ComfyUI installation directory and find 你的安装目录\ComfyUI_windows_portable\update\update_comfyui.bat.
2. Double-click update_comfyui.bat to run the update script and wait for the process to complete.
3. Once the update is finished, restart ComfyUI.

Dependencies and environment updates can be managed similarly.

Upgrading ComfyUI for Manual Git Installations

First, ensure that Git is installed on your computer and that you installed ComfyUI using Git.

1. Open your command line tool and navigate to the ComfyUI directory with:

   cd your_installation_directory/ComfyUI

2. Run the following command to pull the latest ComfyUI code:

git pull

This will update your local repository with the latest changes.

If you want to switch to a different version, you can use:

git log

This command will display the commit history, showing information like:
