Installation does not work with python 3.11.1

I cloned the project and tried to install it with

pip install .

try 'pip install -e .'. I have the same error when I use 'pip install .'

So, I'm getting the same error with python 3.9 on win10 Or to be more precise, I'm trying to install our own local addon (which was based on your example-addon) to the portable version Orange3-3.36.2 While the same procedure worked for version 3.34, 3.36 seems to have problems building the addon.

As suggested by @dddping installing the addon in editable mode works just fine, but doesn't allow the project to be used as portable any longer obviously.

Any help would be appreciated, thank you!

I may have found the problem for my error. The documentation was not build successfully prior to installing the addon.

When running pip install <addon> --verbose, I've found the following entry: Directory 'C:\appl\orange\orange3-voestalpine\doc\_build\html' does not exist. Please build documentation before running bdist_wheel.

After fixing my documentation and rebuilding it with sphinx, the installation worked smoothly.

So just building the docs fixed this? That is a naughty little install script then.
