Additional context

Were you following the "Developer Installation" instructions here? https://gnss-lib-py.readthedocs.io/en/latest/install.html

Did you have any errors when installing gnss_lib_py with poetry install after you cloned the repository ?

When you run the poetry install command you should see a print statement that says gnss_lib_py was installed.

poetry install -r requirements.txt reports following errors at the end.

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
google-auth 2.22.0 requires urllib3<2.0, but you have urllib3 2.1.0 which is incompatible.

After commenting the last line of gnss_lib_py/init.py, poetry run pytest works for me,

# single location of version exists in pyproject.toml
# __version__ = metadata.version("gnss-lib-py")

Hi again, @mikehb I'll need some additional information to be able to help you.

It sounds like you may be interchanging installing with pip vs. poetry and switching between the "Standard Installation" and "Developer Installation" on our Installation page guide.

In the latest poetry, poetry install -r requirements.txt is not valid command. Were you running pip install -r requirements.txt? For the developer installation, the correct installation command is simply running poetry install in the gnss_lib_py directory as shown in the image below:

The error you sent indicates an incompatibility between the version of urllib3 that gnss-lib-py requires and that google-auth 2.22.0 requires. gnss-lib-py has no dependency on google-auth so I'm guessing you're trying to install both packages into the same environment which is causing the problems.

You could try to remedy the issue by either

1. following our developer instructions which use pyenv to isolate gnss-lib-py in its own virtual environment
2. google-auth may have happend to update their dependencies which you could check by upgrading google-auth with pip install --upgrade google-auth then removing gnss-lib-py with pip uninstall gnss_lib_py and starting the installation process again

I was able to install the latest versions of both google-auth and gnss_lib_py without any issues on my computer, so I don't know how else to replicate your problem.

I hope this helps.
