Hi @walnutseal1! I'm Dosu and I’m helping the comfy-cli team.

You're running into "dependency hell" because many custom nodes require Python packages (like cv2, deepdiff, watchdog, numba, gguf, nunchaku, etc.) that aren't installed in your embedded Python 3.13 environment. This is a common issue with portable/standalone ComfyUI setups, especially on Python 3.13, where many scientific and image-processing packages don't yet provide wheels, so installation fails silently or with cryptic errors.

Here’s what’s happening and what you can do:

• Some packages (e.g., cv2, numba, watchdog) do not have wheels for Python 3.13 yet, so even if the manager tries to install them, it fails. This is why you see repeated ModuleNotFoundError for these modules. The same applies to some other dependencies required by custom nodes. The only reliable fix is to use Python 3.12 for now, as most packages support it and ComfyUI is tested with it source.
• ComfyUI-Manager and comfy-cli try to install dependencies by running pip/uv in the embedded Python, but if pip is missing or the package isn't available for your Python version, the install fails (sometimes silently) source.
• If pip is missing in your embedded Python, run python -m ensurepip inside your python_embeded directory to enable package installation source.
• There was a bug in ComfyUI-Manager that broke custom node dependency installation. Update ComfyUI-Manager to at least v3.31.5 to fix this source.
• Some errors are due to version mismatches (e.g., huggingface_hub and diffusers), so you may need to manually align versions or update/downgrade those packages in your embedded Python.
• If you use comfy-cli or pipx/uv to install nodes, make sure dependencies are installed in the same environment as ComfyUI, not in the CLI tool’s own environment source.

What you can do right now:

1. Try running python_embeded\python.exe -m ensurepip to make sure pip is available.
2. Manually install missing dependencies with python_embeded\python.exe -m pip install <package>, but expect failures for some packages on Python 3.13.
3. If you keep hitting missing wheels or build errors, switch to Python 3.12 for your embedded environment.
4. Update ComfyUI-Manager to the latest version.
5. For persistent issues, check if the package has a wheel for Python 3.13 on PyPI. If not, Python 3.12 is your best bet for now.

Let me know if you want step-by-step instructions for switching Python versions or manually installing specific dependencies.

To reply, just mention @dosu.
