pytest fails with 'terminated by signal SIGILL (Illegal instruction)'

Calling pytest from a pipenv raises 'pipenv run pytest' terminated by signal SIGILL (Illegal instruction) when $SHELL is fish 2.7.1 and Illegal instruction: 4 when $SHELL is bash 3.2.

I have opened an issue here because the same version of pytest installed in a conda environment on the same machine executes as expected. I am trying to replicate my conda workflow using pipenv, so testing them side by side.

Please run $ python -m pipenv.help, and paste the results here.

I installed pipenv from homebrew so apparently this does not work.

Expected result

pytest runs my tests as it does in a conda env shown below:

pytest tests/                    
============================= test session starts ==============================
platform darwin -- Python 3.6.3, pytest-3.3.1, py-1.5.2, pluggy-0.6.0
rootdir: /foo, inifile:
plugins: xdist-1.20.1, forked-0.2, cov-2.5.1, hypothesis-3.38.5
collected 1 item

tests/test_pgdb.py .

Actual result

With $SHELL = /usr/local/bin/fish:

pipenv run pytest --collect-only --debug tests/test_pgdb.py
writing pytestdebug information to /foo/pytestdebug.log
============================= test session starts ==============================

fish: 'pipenv run pytest --collect-onl…' terminated by signal SIGILL (Illegal instruction)

With $SHELL = /bin/bash:

pipenv shell

Illegal instruction: 4

Steps to replicate

pipenv 11.7.2, macOS 10.12.6, Mac Pro 5,1

1. Uninstall pytest optional plugins in case they were at issue
2. Either call pipenv shell and then call pytest tests/ or `pipenv run pytest tests/'. Results are identical.

__pycache__ is not where it would be, it’d be in your pip and pipenv caches + in your virtualenv.

I.e. on OSX:

rm -fr ~/Library/Caches/pip
rm -fr ~/Libary/Caches/pipenv
pipenv --rm

For posterity’s sake, installing psycopg2 from source fixed this problem. pipenv’s choice of wheel seems to have been deprecated by the package maintainer. Thanks @jtratner for leading me to the solution.
