Upgraded to Node 5.4.0 via 'brew upgrade,' and then ran 'npm update -g,' which upgraded to npm 3.5.4. npm update finished with warnings:
/usr/local/lib

Running 'npm update -g' (or any other npm command) now throws npmlog errors:

It's not clear to me why the override is happening, or how to point npm to the logs again. Appreciate any thoughts.
