Original GitHub issue: https://github.com/Comfy-Org/desktop/issues/1312

Summary

The --index-url flag in uv has been deprecated and replaced with --default-index. The uv documentation explicitly marks this as "(Deprecated: use --default-index instead)".

Context

When using uv for Python package management, the --index-url option that was previously used to specify a custom package index URL has been deprecated. The new flag --default-index should be used instead for better alignment with uv's modern index management system.

Similarly, --extra-index-url is deprecated in favor of --index.

Impact

Any code or scripts in the ComfyUI Desktop codebase that currently use --index-url with uv commands should be updated to use --default-index to ensure compatibility with future versions of uv.

Migration Examples

Before (deprecated):

uv pip install --index-url https://pypi.org/simple/ package-name
uv pip install --extra-index-url https://custom.index/simple package-name

After (recommended):

uv pip install --default-index https://pypi.org/simple/ package-name
uv pip install --index https://custom.index/simple package-name

Action Required

Search codebase for any usage of --index-url with uv commands
Update to use --default-index instead
Search for --extra-index-url and update to --index
Test to ensure functionality remains the same
Consider migrating to pyproject.toml configuration for more complex index setups

Hi, @webfiltered. I'm Dosu, and I'm helping the desktop team manage their backlog and am marking this issue as stale.

Issue Summary:

You requested updating the ComfyUI Desktop codebase to replace deprecated uv command flags --index-url and --extra-index-url with the new --default-index and --index flags.
The goal is to maintain compatibility with uv's updated package index system and improve index prioritization.
This update would involve codebase-wide replacements, testing, and possibly migrating to pyproject.toml for more complex configurations.
There has been no further activity or comments on this issue since it was opened.
