Start by reproducing the reported node-pre-gyp install --fallback-to-build failure with Node v10.3.0 on Darwin, using the canvas@next installation details and command output as the entry point. Trace the failed completion callback and verify that installation either downloads the binary or completes the fallback build without exiting with code 6.
