Hello and thanks for the question! I’m glad you’re interested in using this package!
For now the registered Mimi models are within our own registry, which you will need to add before you can add an individual model. From the README for MimiRICE2010 (https://github.com/anthofflab/MimiRICE2010.jl):
Preparing the software environment
You first need to connect your julia installation with the central Mimi registry of Mimi models. This central registry is like a catalogue of models that use Mimi that is maintained by the Mimi project. To add this registry, run the following command at the julia package REPL:
pkg> registry add https://github.com/mimiframework/MimiRegistry.git
You only need to run this command once on a computer.
The next step is to install MimiRICE2010.jl itself. You need to run the following command at the julia package REPL:
pkg> add MimiRICE2010
You probably also want to install the Mimi package into your julia environment, so that you can use some of the tools in there:
pkg> add Mimi
