Pipenv App

Simple reference for pipenv usage with dependency links to (private) git repos.

See pipenv dependency (dependency of this project).

New (PEP 508?) way

setup.py

from setuptools import setup
setup(
    name='pipenvapp',
    packages=['pipenvapp'],
    version='0.0.0',
    include_package_data=True,
    # new way
    install_requires=[
        'pipenvdependency @ git+https://github.com/pmlk/pipenv-dependency.git@master'
    ],
    # old way
    # install_requires=['PipenvDependency==0.0.0'],
    # dependency_links=["git+https://github.com/pmlk/pipenv-dependency.git@master#egg=pipenvdependency-0.0.0"],
)

Installation

$ git clone https://github.com/pmlk/pipenv-app.git
$ cd pipenv-app
$ pipenv install -e .

Despite an error the package and its sub-dependencies seem to be installed just fine
(see $ pipenv graph output below). However, the Pipfile.lock is missing.

$ pipenv install -e .

Dependency Graph

In the pipenv-dependency project numpy is required just for kicks.

$ pipenv graph                                                                                                                                                                                                                                                            1 ↵

Old, now deprecated way

The following used to work for pip versions that respected the --process-dependency-link flag.

This approach indirectly makes use of the pip flag --process-dependency-links which is~/was~~ deprecated. ~
Read here and here for more information.

from setuptools import setup
setup(
    name='pipenvapp',
    packages=['pipenvapp'],
    version='0.0.0',
    include_package_data=True,
    install_requires=['PipenvDependency==0.0.0'],
    dependency_links=["git+https://github.com/pmlk/pipenv-dependency.git@master#egg=PipenvDependency-0.0.0"],
)

Installation

# set environment variable for --process-dependency-links
$ export PIP_PROCESS_DEPENDENCY_LINKS=1
$ git clone https://github.com/pmlk/pipenv-app.git
$ cd pipenv-app
$ pipenv install -e .
