it looks like you are using snap rather than the full version of Node-RED. The snap version is restricted to its container so doesn't have access to external build tools required to build the bindings and indeed the serial port plug was for a long time not dynamic - that may have changed (not sure) but would need someone with snap skills to help work it out.

You can use the pi install script to install on Ubuntu. Remove the snap first.
