# Install esmvalcore from a conda lock file
# To build a conda lock file install conda-lock first then
# run conda-lock lock --platform linux-64 -f environment.yml --mamba
# (mamba activated for speed). Change platform for osx-64 or win-64.
# Env creation then happens as per normal use with
# mamba create --name esmvaltool-fromlock --file conda-linux-64.lock
# note that pip and conda are NOT installed.
