You can either install Girder natively on your machine or inside a virtual machine (VM) with Vagrant.
Once you have those installed, obtain the Girder source code by cloning the Git repository on GitHub:
git clone https://github.com/girder/girder.git
Inside of the Girder directory, simply run:
This creates a VM running Ubuntu 18.04, then automatically installs Girder within it. After it completes, Girder will be up and running at http://localhost:9080/ on the host machine.
The VM is linked to your local Girder directory, so changes made locally will impact the Girder instance running in the VM.
To access the VM, run from the Girder directory:
To rebuild the web client:
girder build --dev
