Fix: ModuleNotFoundError: No module named 'pkg_resources' (Stable Diffusion WebUI)

[solowjin23-debug]

During installation, you may encounter errors like:

ModuleNotFoundError: No module named 'pkg_resources'
ERROR: Failed to build CLIP
error: subprocess-exited-with-error

This is caused by:

setuptools >= 82 (removes pkg_resources)
pip >= 24 (pulls incompatible dependencies)

Solution

Force compatible package versions using a constraints file.

Step 1 — Create pip-constraints.txt

In your stable-diffusion-webui root folder, create:
Add the following:

setuptools<82
pip<24
wheel<0.45

Step 2 — Edit webui-user.bat

Open webui-user.bat and add this line:

@echo off

set PYTHON=
set GIT=
set VENV_DIR=
set COMMANDLINE_ARGS=
set PIP_CONSTRAINT=pip-constraints.txt

call webui.bat

Step 3 — Remove broken environment

Delete the existing virtual environment:

stable-diffusion-webui/venv

Step 4 — Run WebUI

Start again:
webui-user.bat

you will get another error "Repository not found:
https://github.com/Stability-AI/stablediffusion.git" then delete the repositories folder and enter in cmd "set COMMANDLINE_ARGS=--skip-install
webui-user.bat"

I struggled with this for over 8 hours with AI and other solutions but it worked

Your going to love this issue. We don't run windows, but we assume it is same issue. Bottom line it comes to correcet versions of pip/python and doing manual install of CLIP.
