running the install script for raspbery (bash curl ...) on raspberry 3b raspbian buster with node version 12.8.3 and npm Version 6.14.6 finishes with no errors (all green), but i do get error starting node-red-start indicating node-red is not fully installed.
It seems that current node red is not fully found in npm! I cant post full install log due to fforum restrictions regarding links, but here is the error part:
Now install Node-RED
