All of the below is using master, checked out at 0fa7bd8bd9be0c64dd14d6c8421b617651d3745d.

pipenv.patched.notpip._internal.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in /Users/greysteil/code/python-test/

Steps to replicate

Run pipenv lock in a directory with the following:

# Pipfile
[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[dev-packages]
"e1839a8" = {path = ".", editable = true}

# setup.py
import setuptools

def _main():
    setuptools.setup(
        packages=setuptools.find_packages(),
        setup_requires=['pbr'],
        pbr=True)


if __name__ == "__main__":
    _main()

--verbose does not help. I still see only this and no other error information:

pipenv.patched.notpip._internal.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in /tmp/tmpjmd83hjxbuild/pyproj/

I don’t have any issues installing that library with pip.

I’m still getting unhelpful errors when there is an installation failure (in my case, a new cftime release was failing because they didn’t upload a wheel and I was missing Cython). Any way to enable the debugging?
