why this resource is not found?

Tried to download(404): https://github.com/node-gfx/node-canvas-prebuilt/releases/download/v2.0.0-alpha.14/canvas-prebuilt-v2.0.0-alpha.14-node-v64-darwin-unknown-x64.tar.gz

There is indeed some problem with this resource missing, however it seems you can compile from the source in that case. You need to download all dependencies, starting from pkg-config "/bin/sh: pkg-config: command not found".
