Pipenv fails when installing packages for python 3.6

Question

I am working on a project that requires pipenv, and python 3.6. When I run pipenv sync, it I get the error messages

An error occurred while installing django-markdown-deux==1.0.5 --hash=sha256:5b4a3cd9454af5b4cec0e19151b41d98d09400ddae0688afb81dbf62a4edafff! Will try again.
An error occurred while installing easy-thumbnails==2.7 --hash=sha256:e4e7a0dd4001f56bfd4058428f2c91eafe27d33ef3b8b33ac4e013b159b9ff91! Will try again.

As well as a privately maintained library withheld for privacy reasons (I have tried to remove this, it does not help.) pipenv then tries to "Installing initially failed dependencies…", before spewing out a wall of errors of like

This error message, formatted slightly differently comes also when trying to install easy-thumbnails via pipenv.

I have pipenv version version 2020.8.13, and have tried to install several different versions of python 3.6 (4, 12, 11) via pyenv, as well as via conda. The same error persists, while we are not able to reproduce the error on other systems. I am using Ubuntu

Answer 1

In my case, I must re-install setuptools to fix this issue:

pip install --upgrade --force-reinstall setuptools

Answer 2

In my case none of the above solutions worked but this one did

pipenv run pip install --upgrade setuptools

Answer 3

I was struggling with moto dependency:

pipenv run pip install --upgrade setuptools fixed the issue.

then pipenv install moto

Answer 4

try this

.venv/bin/pip3 install --upgrade setuptools

Answer 5

Check if installing via python -m pip <package_name> or python -m pipenv install works.
