im trying to install Truffle and have run into numerous problems - made some headway after getting an earlier version of python but camt seem to figure out this error - could someone point me in the right direction?

/Users/B.Booi/.npm-global/bin/truffle -> /Users/B.Booi/.npm-global/lib/node_modules/truffle/build/cli.bundled.js

keccak@1.4.0 install /Users/B.Booi/.npm-global/lib/node_modules/truffle/node_modules/keccak npm run rebuild || echo "Keccak bindings compilation fail. Pure JS implementation will be used."

keccak@1.4.0 rebuild /Users/B.Booi/.npm-global/lib/node_modules/truffle/node_modules/keccak node-gyp rebuild
