Duplicate of #1662. Not sure when this will happen since I'm still struggling to get x86/64 prebuilds working again.

See also, from #1511, another place to track this issue:

Prebuilds aren't available for ARM. Please see the wiki for guides on building from source. See also node-gfx/node-canvas-prebuilt#69.
