Installation fails with older pip due to missing wheels

[msullivan]

I get the error:

It works on 3.6/3.7 and it works on linux.

I think maybe setuptools_scm needs to be specified in setup.cfg as setup_requires?

I have the same issue but for python 3.7 on Windows:

I think maybe setuptools_scm needs to be specified in setup.cfg as setup_requires?

It's used in setup.py already: setup_requires=['setuptools_scm'],

The problem appears to be that setuptools_scm fails to install:

Couldn't find index page for 'setuptools_scm' (maybe misspelled?)
Download error on https://pypi.org/simple/: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056) -- Some packages may not be found!

[blueyed]

Please try with the latest pip.

[msullivan]

Seems to work with pip 19.3

[RonnyPfannschmidt]

lastest pip works around broken ssl of the osx python

[campbellr]

Could this also be due to the fact that the latest 2 releases of pytest-forked don't have any wheels published on pypi (earlier versions do)? Any chance someone could publish wheels for 1.1.0?

I have the same problem (i haven't tried upgrading to the latest version of pip yet) with the latest build but not with older build because installing the wheel bypasses all the setup.py stuff...

[campbellr]

Since this is closed, is it worth filing another issue to ask for wheels?

[blueyed]

According to https://github.com/pytest-dev/pytest-forked/blob/dd42fd1861201536f985be7075f8cd869e17179c/.travis.yml#L30 it should include a wheel? Check the build log for it maybe? /cc @untitaker

[untitaker]

We should fix this. The build log is in Travis. I thought the 1.1.1 had wheels though. I know that 1.1.0 didn't

[RonnyPfannschmidt]

travis never ever had a well working pypi deploy story

[tucked]

Related: #26

[untitaker]

@tucked should I make a new release to try again?

[tucked]

@untitaker That would be great :)

[untitaker]

Pushed 1.1.2, let's see what travis does with it

[untitaker]

ugh

https://github.com/pytest-dev/pytest-forked/commit/ce7d9616359697c196158b9d19b599b0f90d6531

Ok let's try again

[tucked]

Oh, nice catch!

[untitaker]

1.1.3 has wheels

[tucked]

FWIW, 1.1.2 works for us even with no wheel 😎 Anyways, thanks for jumping on this!

[untitaker]

I don't know what's going on in that pyproject.toml but it's all good I guess!
