pip-compile raising AssertionError on its logging handler

Question

I have a dockerfile that currently only installs pip-tools

FROM python:3.9

RUN pip install --upgrade pip && \
    pip install pip-tools

COPY ./ /root/project

WORKDIR /root/project

ENTRYPOINT ["tail", "-f", "/dev/null"]

I build and open a shell in the container using the following commands:

docker build -t brunoapi_image .
docker run --rm -ti --name brunoapi_container --entrypoint bash brunoapi_image

Then, when I try to run pip-compile inside the container I get this very weird error (full traceback):

root@727f1f38f095:~/project# pip-compile
Traceback (most recent call last):
  File "/usr/local/bin/pip-compile", line 8, in <module>

  File "/usr/local/lib/python3.9/site-packages/piptools/repositories/pypi.py", line 455, in _setup_logging
    assert isinstance(handler, logging.StreamHandler)
AssertionError

I have no clue what's going on and I've never seen this error before. Can anyone shed some light into this?

Answer 1

As of now, it is enough to upgrade pip-compile via:

pip install --upgrade pip-tools

since the bug @SEDaradji mentioned is resolved.

Answer 2

It is a bug, you can downgrade using:

pip install "pip<22"
