Hello!
To package zeitgeist, I need python2-rdflib. With python 3, there was no
problem, but with python 2, there seems to be a dependency on sparqlwrapper:
...
Installed /gnu/store/kxd0yf301yz53cp8lyn7acyha78sfcjk-python2-rdflib-4.1.2/lib/python2.7/site-packages/rdflib-4.1.2-py2.7.egg
Processing dependencies for rdflib==4.1.2
Searching for SPARQLWrapper
Reading https://pypi.python.org/simple/SPARQLWrapper/
Download error on https://pypi.python.org/simple/SPARQLWrapper/: [Errno -2] Name or service not known -- Some packages may not be found!
Couldn't find index page for 'SPARQLWrapper' (maybe misspelled?)
Scanning index of all packages (this may take a while)
Reading https://pypi.python.org/simple/
Download error on https://pypi.python.org/simple/: [Errno -2] Name or service not known -- Some packages may not be found!
No local packages or download links found for SPARQLWrapper
error: Could not find suitable distribution for Requirement.parse('SPARQLWrapper')
phase `install' failed after 1 seconds
But sparqlwrapper depends on rdflib (I tried it out, and its web page
also states this). How is this possible, and how is it solved?

Looking at the code of both modules on github, there is:
https://github.com/RDFLib/sparqlwrapper/blob/master/requirements.txt
rdflib
rdflib_jsonld
and
https://github.com/RDFLib/rdflib/blob/master/requirements.py2.txt
flake8
isodate
pyparsing<=1.5.7
SPARQLWrapper
(and similarly for python3; no idea why there the installation worked
without sparqlwrapper).
So what can we do?

It appears that SPARQLWrapper is not really needed and you can disable
dependency guessing with '--no-guessing-deps'. See
https://sources.debian.net/src/rdflib/4.1.2-3/debian/rules/

Thanks for the suggestion! This seems to be some debian specific macro in
their package recipes; I tried it as a configure flag, and setup.py chokes
on it.
However, there are these lines in setup.py:
kwargs['install_requires'] = [
'isodate',
'pyparsing', 'SPARQLWrapper']
explicitly in the "else" branch of
if sys.version_info[0] >= 3:
So this would explain why there was no problem with python-3.
I would suggest to patch this 'SPARQLWrapper' away. What is the recommended
way nowadays? A patch, I suppose? Or a snippet?
There is another occurrence of SPARQLWrapper in rdflib.egg-info/requires.txt.
But I suppose this is merely documentation?

In Python 3, it is not in "install_requires", but it is in "requires":
https://github.com/RDFLib/rdflib/blob/master/setup.py#L43
Not sure exactly what the difference is, though.
Cyril.

I saw it, maybe it means that it needs to be installed together with
sparqlwrapper?
Anyway, I removed the dependency for python 2. Then for the tests, it needed
python2-nose. Then a lot of tests failed.
I am giving up for now. I could disable the tests, and go on with
sparqlwrapper, zeitgeist and libqzeitgeist (my real aim!), but how would
one know that the resulting libraries actually work?
