pkg_resources Missing in ComfyUI

Telemetry snapshot queried on April 17, 2026: 92 events across 9 installs for comfyui_fatal_error_detected.

What telemetry shows

• A missing pkg_resources import usually means the Python packaging layer is damaged.
• This is more structural than a one-off optional backend warning.

What users usually notice

• Several plugins fail with package discovery or entry-point errors.
• Logs say No module named pkg_resources.

What to do next

1. Repair pip and setuptools in the same ComfyUI environment.
2. Restart and retest the plugins that failed.
3. If the environment is still inconsistent, rebuild it instead of stacking more package mutations.

Escalate when

• Fresh environments still miss pkg_resources after the baseline install.
• Repairing setuptools triggers a wider dependency conflict chain.
