Conda press produces an unsupported or invalid wheel

[jcarpent]

Dear all,

First of all, thanks a lot for this very nice option to produce wheels directly from conda.
I'm facing some errors when trying to install a wheel generated by conda-press saying that the wheel is an unsupported or invalid wheel.
Have you already face such an issue?

Below are the lines that I'm running on my computer:

conda create -n test-pip python=3.7 anaconda
conda config --add channels conda-forge
conda press --subdir osx-64 --fatten pinocchio=2.2.1=py37hd4e088a_1
 pip install pinocchio-2.2.1-1_py37hd4e088a-cp37-cp37m-macosx_10_9_x86_64.whl --no-clean --no-deps

And the results that I've obtained:

Processing ./pinocchio-2.2.1-1_py37hd4e088a-cp37-cp37m-macosx_10_9_x86_64.whl
WARNING: No metadata found in /private/var/folders/68/bnm8hh8s4119fpn4p7wv6zw400m57h/T/pip-install-cf5lgniw/pinocchio

ERROR: pinocchio is in an unsupported or invalid wheel

Thanks in advance for your help!
