Afterwards, simply activate the environment and run the following command to check if the installation process was successful.

conda activate my-project
python -m compas
Yay! COMPAS is installed correctly!

Known Issues

If you encounter a problem that is not described here, please file an issue using the Issue Tracker.

Installing Planarity

The installation process with pip can fail while installing planarity, because cython is not installed. If this is the case, install cython using pip (or conda), before installing COMPAS.

pip install cython --install-option="--no-cython-compile"
pip install COMPAS

Microsoft Visual C++ Build Tools

The installation with pip can fail because “Microsoft Visual C++ Build Tools are missing”. To install the Microsoft Visual C++ Build Tools choose one of the options provided here: https://www.scivision.dev/python-windows-visual-c-14-required/ and just follow the instructions. Then run the pip installation commands again.
