installs wrong multiprocess wheel for pypy

[mmckerns]

Travis CI installs the wrong multiprocess wheel when for pypy3.6 and pypy3.7.
A pathos pypy3.6 install identifies multiprocess-0.70.12.2-py36-none-any.whl as a dependency

Note that both do not install the pypy-specific versions (i.e. multiprocess-0.70.12.2-pp36-none-any.whl), and the latter also installs the wrong version of python (i.e. 3.6 instead of 3.7).

a pathos pypy2.7 also installs the wrong multiprocess dependency (zip not whl):

Seems similar issue exists for a local install as well...

Possibly due to badly named multiprocess wheel... however, pypy3.7 installing a py3.6 wheel is very odd.

[mmckerns]

It appears as pip moved from 19.x to 20.x, the supported naming conventions for pypy changed: pypa/packaging#311
pypa/pip#7629

Thus pp37-none-any.whl (used by multiprocess) is no longer supported:

$ pypy3.7
>>>> from packaging import tags
>>>> for t in tags.generic_tags(): print(t)
pp37-pypy37_pp73-macosx_***
[SNIPPED]
pp37-none-macosx_***
[SNIPPED]
>>>> for t in tags.compatible_tags(): print(t)
[SNIPPED]
py37-none-any
py3-none-any
py36-none-any
py35-none-any
py34-none-any
py33-none-any
py32-none-any
py31-none-any
py30-none-any

Same for pp36-none-any.whl and pp27-none-any.whl.

Workaround added for travis (force a source install): 835a3fd. The issue still remains for a non-travis install.

[mmckerns]

should be fixed by the release of multiprocess-0.70.13
