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()

[techalchemy]

I think #2314 handles this— can you check?

[greysteil]

Just checked - sadly not 😢.

[uranusjr]

I did some digging. The exception you see is masking the real error, which can be obtained if you run python setup.py egg_info directly:

λ .venv\Scripts\python.exe setup.py egg_info
Traceback (most recent call last):

    'The setup.cfg file %s does not exist.' % path)
distutils.errors.DistutilsFileError: The setup.cfg file C:\Users\uranusjr\Documents\playground\pbr-test\setup.cfg does not exist.

PBR requires a setup.cfg containing needed information, but you’re not providing it.

We need to somehow get Pipenv to display the underlying error instead of a generic “Command "python setup.py egg_info" failed with error code 1”. It is really unhelpful.

[MarkLodato]

Is there a workaround when one gets this error message? I am new to pipenv and virtualenv so I am not sure what to do next. Can I use an older version of pipenv or pip? Run some command manually?

[MarkLodato]

Nevermind. In my case, the root cause was #2584.

[techalchemy]

Thanks for the info, that may be a secret culprit on a lot of related issues now that you mention it...

[techalchemy]

This will be reported better in the next release

Error:  An error occurred while installing -e .!

This is likely caused by a bug in -e .. Report this to its maintainers.

[astrojuanlu]

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?

[techalchemy]

--verbose will likely help

[nickwilliams-eventbrite]

--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.

[sewagodimo]

I am getting the same error as @nickwilliams-eventbrite
I also don't get the error when using pip

[alexykot]

I'm facing a similar problem with installing pysqlite via pipenv install. If I try to pip install pysqlite, I get the following error:

[alexykot@alexykot-T580 project]$ 
Collecting pysqlite
  Using cached https://files.pythonhosted.org/packages/42/02/981b6703e3c83c5b25a829c6e77aad059f9481b0bbacb47e6e8ca12bd731/pysqlite-2.8.3.tar.gz
    Complete output from command python setup.py egg_info:
    pysqlite is not supported on Python 3. When using Python 3, use the sqlite3 module from the standard library.
    
    ----------------------------------------

This makes sense and is a meaningful response.

However when I run pipenv install while having pysqlite = "*" in the [packages] section - I'm getting a long stack trace and meaningless

...
pipenv.patched.notpip._internal.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in /tmp/tmpplvb860ubuild/pysqlite/``` 

The original error is no longer there, and this is not helpful. Seems like pipenv is swallowing the original response and conceals useful messages.

can u try the master branch and see what it prints?
