# ComfyUI Migration to UV Package Manager
|
|
|
|
## What is UV?
|
|
|
|
[UV](https://github.com/astral-sh/uv) is a modern Python package installer and resolver written in Rust. It serves as a drop-in replacement for pip with significant performance improvements:
|
|
|
|
- **Speed**: UV installs packages 10-100x faster than pip
|
|
- **Reliability**: Better dependency resolution to avoid conflicts
|
|
- **Compatibility**: Works with existing requirements.txt files
|
|
- **Modern**: Built with Rust for performance and safety
|
|
|
|
## Why Migrate from pip to UV?
|
|
|
|
- Faster installation of dependencies
|
|
- Improved virtual environment management
|
|
- Better handling of dependency conflicts
|
|
- Consistent installation experience across platforms
|
|
- Compatibility with existing pip workflows
|
|
|
|
## Installation
|
|
|
|
Install UV:
|
|
|
|
```bash
|
|
# Install UV
|
|
curl -LsSf https://astral.sh/uv/install.sh | sh
|
|
|
|
# Add to PATH (bash/zsh)
|
|
source $HOME/.local/bin/env
|
|
|
|
# Or for fish shell
|
|
# source $HOME/.local/bin/env.fish
|
|
```
|
|
|
|
## Using UV with ComfyUI
|
|
|
|
### Basic Usage
|
|
|
|
```bash
|
|
# Create a virtual environment
|
|
uv venv
|
|
source .venv/bin/activate # On Linux/macOS
|
|
# .venv\Scripts\activate # On Windows
|
|
|
|
# Install dependencies
|
|
uv pip install -r requirements.txt
|
|
|
|
# Install advanced dependencies (if needed)
|
|
uv pip install -r requirements_advanced.txt
|
|
```
|
|
|
|
### UV Native Commands
|
|
|
|
Instead of using the pip-compatible interface, you can use UV's native commands:
|
|
|
|
```bash
|
|
# Install packages
|
|
uv add packagename
|
|
|
|
# Install dev dependencies
|
|
uv add --dev pytest black
|
|
|
|
# View dependency tree
|
|
uv tree
|
|
|
|
# Update dependencies
|
|
uv sync
|
|
```
|
|
|
|
## Migration Tips
|
|
|
|
1. UV is designed to be a drop-in replacement for pip, so most commands work similarly
|
|
2. Existing requirements.txt files are fully compatible
|
|
3. For best results, start with a fresh virtual environment
|
|
4. UV includes built-in lockfile support for reproducible environments
|
|
|
|
## Troubleshooting
|
|
|
|
If you encounter issues:
|
|
|
|
- Ensure you have the latest version of UV: `uv self update`
|
|
- Try running with verbose output: `uv -vvv pip install -r requirements.txt`
|
|
- Check the [UV documentation](https://github.com/astral-sh/uv) for known issues
