NameError: name '__version__' is not defined
Hi, I have two applications. One uses the system version of Python, which is 3.6.8, whereas the other uses Python 3.10.8 installed in a non-system path. For both applications I am using poetry with a pyproject.toml file which contains the version information and __init__.py at the root which contains try: import importlib.metadata as importlib_metadata except ModuleNotFoundError: import importlib_metadata __version__ = importlib_metadata.version(__name__) For the application with the system Python this mechanism works, but for the non-system Python I get the error: NameError: name '__version__' is not defined For the 3.6 application I have PYTHONPATH=/nfs/local/lib/python3.6/site-packages PYTHONUSERBASE=/nfs/local PYTHON_VERSION=3.6 PYTHON_VIRTUALENV= and for the 3.10 application I have PYTHONPATH=/nfs/easybuild/software/Python/3.10.8-GCCcore-12.2.0/easybuild/python:/nfs/local/lib/python3.10/site-packages PYTHONUSERBASE=/nfs/local PYTHON_VERSION=3.10 PYTHON_VIRTUALENV= The applications are installed in /nfs/local/lib/python3.6/site-packages and /nfs/local/lib/python3.10/site-packages, respectively. Can anyone see where this is going wrong? I thought it should be enough that the packages with the metadata is available via PYTHONPATH, but this seems not to be sufficient. So I must be overseeing something. Cheers, Loris -- This signature is currently under constuction. -- https://mail.python.org/mailman/listinfo/python-list

If in the 3.10 application I add
print(f"__init__ Version: {__version__}")
to __init__.py the correct version is printed. So the problem is that
the variable is not available at the point I am trying access it. The
relevant code (a far as I can tell) in main.py looks like this:
import typer
app = typer.Typer()
@app.callback()
def version_callback(value: bool):
if value:
typer.echo(f"Version: {__version__}")
raise typer.Exit()
@app.callback()
def common(
ctx: typer.Context,
version: bool = typer.Option(None, "--version",
help="Show version",
callback=version_callback),
):
pass
if __name__ == "__main__":
app()
This is the first time I have used typer, so it is more than likely that
I have made some mistakes.

Loris

OK, I worked it out. Instead of
typer.echo(f"Version: {__version__}")
I need
typer.echo(f"Version: {mypackage.__version__}")
Thanks for the help :-)
Even if no-one replies, it still helps me to have to formulate the
problem for an audience of people who probably know more than I do.

The traceback informs you about the calling context that led to the exception, espeically where in the code the exception occurred. If you cannot resolve the problem at your own, include the traceback in your call for assistence. -- https://mail.python.org/mailman/listinfo/python-list
