Description
I'm encountering an error while trying to install the cmeel-octomap package using pip within a Python 3.13 virtual environment. The installation process completes up to the build phase but fails during the test execution. Below are the detailed steps and the complete error log for reference.
Steps
Create a Python 3.13 virtual environment:
python3.13 -m venv .venv
Activate the virtual environment:
source .venv/bin/activate
Verify Python version:
python --version
# Output: Python 3.13.1
Upgrade pip to the latest version:
pip install pip --upgrade
Attempt to install cmeel-octomap:
pip install cmeel-octomap<2,>=1.9.8.2
The installation fails during the metadata preparation and testing phase after building the package. Specifically, one of the tests (test_color_tree) fails, causing the entire installation process to abort.
