Answer 1

In my case I noticed that the Windows SDK version didn't have the 'irprops.lib' as it has been replaced according to: https://blogs.windows.com/windowsdeveloper/2019/11/19/windows-10-sdk-preview-build-19023-available-now/

Removal of IRPROPS.LIB

In this release irprops.lib has been removed from the Windows SDK. Apps that were linking against irprops.lib can switch to bthprops.lib as a drop-in replacement.

To solve it I installed a previous version of the Windows 10 SDK. If I had more time I probably would try to update the dependency to bthprops.lib;)

Answer 2

This is now fixed in the github repo but it looks like they haven't updated the pip package. installing from the repo directly worked without having to downgrade

Answer 3

• I installed VS Code onto my windows 10 box.

• I downloaded and installed in a separate step, the MS VS 10 build library. (It is big.)

• Download the pybluez zip file from their github, and unzip it. Dont use pip to install it because pybluez's setup.py is now wrong (outdated).

• Change pybluez library's setup.py file to say bthprops.lib because irprops.lib does not exist any more. (You can have your file editor search in the file for props.lib for convenience.)

• I activated my projects python virtual environment.

• At command line, in the new directory you extracted the lib to, run the usual python installation command for libraries: python setup.py install

This is what actually got it working here. The key it turns out, is to hand-modify the setup.py file, which you only can do by first downloading the zip file of pybluez, which contains a setup.py file that you can modify, instead of using pip, which you can't modify the setup.py file that's in there.
