ComfyUI for Linux (Install Script) / Windows (Portable Version)
Linux
first open the script in a text editor and adjust the path and versions, currently its:
BASE_PATH="/mnt/data/AI" # Parent directory for ComfyUI, venv, models, output, custom_nodes, All paths will be derived from this base path
PYTHON_VERSION="3.12.10" # Python version to install via pyenv
PYENV_ROOT="${PYENV_ROOT:-$HOME/.pyenv}" # pyenv installation directory
PYTORCH_VERSION="2.9" # PyTorch major.minor version for wheel URLs (e.g., 2.9, 2.10)
PYTORCH_FULL_VERSION="2.9.1+cu128" # Full PyTorch version for package installation (e.g., 2.9.1+cu128, 2.10.0+cpu)
PYTORCH_INDEX_URL="https://download.pytorch.org/whl/cu128" # PyTorch index URL (cu128, cu121, cpu)
NUMPY_VERSION="2.2.6" # NumPy version (2.2.x compatible with PyTorch 2.9+)
TRANSFORMERS_VERSION="4.57.3" # Transformers version (5.x for Qwen3-VL/Mistral3 support)
COMFYUI_FRONTEND_VERSION="1.37.11" # ComfyUI frontend version (installed in venv's site-packages)
COMFYUI_DIR_NAME="ComfyUI" # ComfyUI folder name (change if you want a different name)
COMFYUI_VERSION="v0.12.1" # ComfyUI version to checkout (tag, branch, or commit SHA). Leave empty for latest.
CREATE_SYMLINKS=true # Set to false to skip all symlink creation
SYMLINK_CUSTOM_NODES=true # Set to false to keep custom_nodes as a regular directory (only applies if CREATE_SYMLINKS=true)
INSTALL_NUNCHAKU=true # Set to false to skip Nunchaku (NVIDIA GPU required)
to execute the script open a bash in the folder where you've extracted the file and type chmod +x install_comfy_env.sh after that you can execute it with ./start-comfyui.sh
if you do all steps (default) the script will:
install pyenv (if not existing),
the selected python version,
create the comfy_env (venv) and
installs comfyui.
it also clones a set of custom nodes that are needed for my workflows (check the script, the block starts at line 551).
in its current state it installs python 3.12.10, pytorch 2.9.1 cu128, nunchaku 1.2.1 package, facexlib, insightface etc. it installs the requirements of all cloned custom nodes.
it also adds code to the .bashrc if selected. that way you can start comfyui faster by typing comfyui in the bash. but it also creates a startup script that allows you to start comfyui (make it executable and execute it).
the final steps in the script is forcing the versions that are setup at the beginning. e.g. pytorch 2.9.1, transformers 4.57.3, numpy 2.2.6 because those are most likely overwritten by the requirements of the custom nodes (like reactor, facenet_pytorch etc.).
for the different distros there is a package manager detection so it should work no matter what distro you use. this is only used for the pyenv/python setup in Step 1 all other installations are done with pip.
Debian/Ubuntu: apt-get
Fedora/RHEL: dnf (my system)
CentOS/older RHEL: yum
Arch Linux: pacman
openSUSE: zypper
in the last update i've added step 11 which creates 2 aliases now
comfyui (starts comfyui directly)
envact (activates the venv)
I've also added a Multi-shell detection to write the aliases to the correct files:
Bash → adds aliases to ~/.bashrc
Zsh → adds aliases to ~/.zshrc
Fish → adds functions to ~/.config/fish/config.fish (Fish uses different syntax)
Fallback → uses ~/.profile if no common shells detected
since im not using windows anymore there will be no further updates for the portable versions 🤷🏻.
Version 0.8.2
pyTorch 2.9+cu128
python: 3.12.10
Frontend: 1.36.13
removed crystools -> replaced with crystools-monitor only
Even though some API imports have been fixed, the deprecated messages are still displayed.
the reason for adding the forked versions instead of the originals is that some of the nodes are currently not working with the latest comfyui version.
