Can't install Poetry in Ubuntu 20.04 Docker image due to setuptools error
Question:
I’m trying to build the following Dockerfile:
FROM ubuntu:20.04
RUN apt-get update &&
apt-get install -y curl software-properties-common &&
add-apt-repository ppa:deadsnakes/ppa &&
apt install -y python3.11 python3.11-distutils &&
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.11 &&
python3.11 -m pip install poetry==1.2.2
However, it fails to install poetry with the following error message:
Collecting msgpack>=0.5.2
Downloading msgpack-1.0.4.tar.gz (128 kB)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 128.1/128.1 kB 15.2 MB/s eta 0:00:00

File "<frozen importlib._bootstrap>", line 1178, in _find_and_load
File "<frozen importlib._bootstrap>", line 1142, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'setuptools'
If I replace the install command for Poetry at the end and replace it with python3.11 -m pip list then the output clearly shows setuptools being installed:
Package Version
------------------- -----------
...
setuptools 67.2.0
...
I can also import setuptools without problems when I open a Python interpreter. What is going on?
Note that I’m unable to use a newer Ubuntu version or pythonX.Y image due to other requirements.
Answers:
Don’t install poetry into the global Python environment (nor into your project venv), or it’ll influence package compatibility within your project/system dependencies.
See poetry docs on how to give poetry its own venv when doing a "manual install". Otherwise, use the official poetry install script which does that for you.
