Building a Python Wheel with setuptools throws error Function not implemented: '<package_name>.egg-info/dependency_links.txt'

Question

Problem

I'm trying to build a Python Wheel using this guide.

The issue is that whenever I run python setup.py sdist bdist_wheel it gives an error:

Function not implemented: '<package_name>.egg-info/dependency_links.txt'

A screenshot of the error message can be found here

Environment

The environment is a Jupyter Lab terminal, which runs on an Ubuntu VM (16.04.6 LTS) in Azure.

Code

The directory containing the project code looks like this:

project_name/

└── package_name/

        └── __init__.py

        └── script_name.py

└── setup.py

The __init__.py script contains this line:

from . import script_name

The setup.py script contains this:

from setuptools import setup, find_packages

setup(
    name="package_name",
    version="0.0.1",
    description="description of the package",
    
    author="Me",
    author_email="me@email.com",
    
)

Tried so far

So far I've checked:

• That the pip, setuptools and wheel packages are always up to date
• On multiple different VMs I get this error
• On a Windows 10 laptop it works

Any help would be appreciated!

Answer 1

It turns out this issue was caused by trying to build a wheel from code stored in a mounted storage account on Azure.

The solution we ended up with is to copy the project directory to a temporary location directly on the VM (using mktemp) and build the wheel there.
