The easiest way to install netCDF-SCM is with conda
# if you're using a conda environment, make sure you're in it conda install -c conda-forge netcdf-scm
It is also possible to install it with pip
# if you're using a virtual environment, make sure you're in it pip install netcdf-scm
However installing with pip requires installing all of Iris’s dependencies yourself which is not trivial. As far as we know, Iris cannot be installed with pip alone.
