Installation fails with “ERROR: Could not build wheels for celerite2 which use PEP 517 and cannot be installed directly”
This error message may appear when upgrading to pycheops version 0.9.1 or later. The working solution is to install celerite2 prior to installing/ updating pycheops using:
git clone --recursive https://github.com/dfm/celerite2.git
python -m pip install celerite2==0.0.1rc1
