Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libffi', required by 'gobject-2.0', not found
gyp: Call to 'PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig pkg-config --cflags librsvg-2.0 cairo-png cairo-pdf cairo-svg' returned exit status 1 while in binding.gyp. while trying to load binding.gyp

This project is no longer maintained.

If you have any issues, you can try prebuilt node-rsvg or create your own fork.
