Download and run the SPARKL self-installer
The self-installer is a self-contained shell file on the SPARKL GitHub repository
curl -LO https://github.com/opensparkl/sse_core/releases/download/v1.3.3/sse-Darwin-18.2.0-x86_64.sh
Run the installer and follow the prompts. The installer needs write permission to the installation directories which by default are under
sudo sh ./sse-Darwin-18.2.0-x86_64.sh
Create a SPARKL node directory in (say) your home directory
Change into your node directory and start an sse in it
cd ~/mynode sse start
Check the sse has started ok
Now would be a good time to install the SPARKL CLI.
Or, you can point your browser at http://localhost:8000.
