MOOSE Development Environment

Create a unique conda environment for MOOSE development, named moose, and install the MOOSE dependency packages:

conda create -n moose moose-dev=2026.05.08=mpich

After the installation completes, activate the new environment:


conda activate moose

If you are on a Macintosh machine, a supported version of the Mac OS X Software Development Kit (SDK) is required to use this environment. If a supported version has not been installed, an error will appear when calling the previous activation command. Follow the instructions in the error message to install a supported version of the SDK.

If you are running into errors, please see our troubleshooting guide for Conda.
