Re: Allow installation on buster of a package not supporting 3.7 (async/await syntax error when generating bytecode)

Thanks a lot Nicolas !

It looks perfect, I made the modification but haven't been able to test it yet.

Hello list,


I have a package working perfectly fine on Pyrhon 3.6 but using async/await
methods so it cannot work on python 3.7 at the moment.
During package compilation, I popd 3.7 from supported version returned by
py3version and it allows me to build the package just fine:

Problem: I cannot install it. Despite 3.7 was not "enabled" during build,
when installing debian helpers try to compile bytecode for both 3.6 and 3.7
and fails. Is there any way to workaround that ?

You can use the bcep (bytecompile exception pattern) mechanism. The
documentation can be found in dh_python3(1)[1] and
/usr/share/doc/dh-python/README.PyDist, and you can find some examples in
codesearch.

HTH,
