Unable to convert "entrypoints" package

Trying to run pyp2rpm entrypoints fails with the following traceback:

Traceback (most recent call last):
  File "/usr/lib/python3.4/site-packages/pyp2rpm/archive.py", line 353, in json_wheel_metadata

During handling of the above exception, another exception occurred:

Using pyp2rpm 3.0.2 in Fedora 23.

Maybe related to the fact there are no source packages on PyPI? See takluyver/entrypoints#5.

[hroncok]

Wow, that one is quite different, so even if it works trough this, it will find no setup.py etc. I wonder if this should be fixed, and if so then how. Maybe a proper solution would be just to produce a nicer error?

Tarball is not present so pyp2rpm tries to extract metadata from wheel. There is also something wrong with the wheel. I've downloaded it mannualy and tried to unpack it, this was the result:

$ wheel unpack entrypoints-0.1-py2.py3-none-any.whl

Unpacking to: ./entrypoints-0.1

That unpacking seems to work fine to the latest entrypoints-0.2.2-py2.py3-none-any.whl.

[QuLogic]

Also, I see no mention of the searched-for metadata.json or pydist.json in the Wheel spec.

[mcyprian]

Description of metadata files content is in PEP 426.

Nicer error in case of missing sources was implemented in ada77670, closing this.
