Error on: "Task: [Install Docker Compose using Pip]" - Fix here.

[hockeygoalie35]

Hi, so due to an issue with PyYAML5.4.1, the wheel for PyYAMLcan't be built. This is due to an issue with v5.4.1. This issue was apparenly caused by an incompatibility of PyYAML<6.0.1 compiled under the version of Cython>=3.0.

The Fix: Change docker.yml starting at line 52 in the Tasks folder:

name: Install Docker Compose using Pip.
  ansible.builtin.pip:
    name: 
      - pyyaml==5.3.1
      - docker-compose
    state: present
    executable: pip3

This ensures the previous version of PyYAML is pulled until 6.0.1 is released.

On Debian 12, the above change did not work until I also deleted the /usr/lib/python3.11/EXTERNALLY-MANAGED file.

Hi, for me the error on that step was:

fatal: [172.16.1.142]: FAILED! => {"changed": false, "cmd": ["/usr/bin/pip3", "install", "pyyaml==5.3.1", "docker-compose"], "msg": "\n:stderr: error: externally-managed-environment\n\n× This environment is externally managed\n╰─> To install Python packages system-wide, try apt install\n python3-xyz, where xyz is the package you are trying to\n install.\n \n If you wish to install a non-Debian-packaged Python package,\n create a virtual environment using python3 -m venv path/to/venv.\n Then use path/to/venv/bin/python and path/to/venv/bin/pip.

So I decided to be wild and pass --break-system-packages so the entries look like that now:

name: Install Docker Compose using Pip.
  ansible.builtin.pip:
    name: 
      - pyyaml==5.3.1
      - docker-compose
      - --break-system-packages
    state: present
    executable: pip3

It work!

PS: My Pi OS is Ubuntu Server 23.10

This fixed the problem for me (Debian 12):

$ pip3 install "cython<3.0.0" wheel --break-system-packages
$ pip3 install pyyaml==5.4.1 --no-build-isolation  --break-system-packages
$ pip3 install docker-compose

pip3 install docker-compose

Tried this for RPI5 but didn't work still get:
