First tell us exactly what you do. Do you start GRASS first (how was GRASS installed, which version?), then what? The first message suggests a failed GRASS installation. Can you use GRASS at all? Try to run any regular example on the data in your location in
GRASS to check that GRASS works before anything else.</p>
