I am using Yocto Kirkstone to create an image for my Linux device. I want to add the PyPi package 'tinydb' that does not already exist as a bitbake recipe. I have used a tool to create a working recipe that I can bitbake. However, when I try to include this recipe into my image, I get the following failure. So I can build the package but not install it. How can I fix this? Thanks.
Reading package lists...
Building dependency tree...
Reading state information...
Package python3-tinydb is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'python3-tinydb' has no installation candidate
However I can successfully do this:
bitbake -c cleansstate python3-tinydb && bitbake python3-tinydb
Bitbake recipe:
# The is automatic generated Code by "makePipRecipes.py"
# (build by Robin Sebastian (https://github.com/robseb) ([email protected]) Vers.: 1.2)

EDIT: I believe maybe the issue is that there is no 'package' in the work directory for Yocto. This may be because there is not setup.py to install the tinydb package:

I think it is not enough inherit only pypi for your bitbake recipe in case of TOML. Try to use inherit pypi python_poetry_core.
As i see tinydb uses the new pyproject.toml mode without setup.py. There is a similar question here.

Souliton is to use python_poetry_core or also you can make a custom do_configure:prepend() which can generate a simple setup.py.
