Okay now uibuilder is not giving any errors, but I'm getting these in console:

1 May 20:37:47 - [warn] [node-red-contrib-rfxcom/rfxcom] Error: The module '/home/mat/.node-red/node\_modules/@serialport/bindings/build/Release/bindings.node'  
was compiled against a different Node.js version using  
NODE\_MODULE\_VERSION 57. This version of Node.js requires  
NODE\_MODULE\_VERSION 64. Please try re-compiling or re-installing  
the module (for instance, using `npm rebuild` or `npm install`).

Also, Dashboard isn't working! I get "Please add some UI nodes to your flow and redeploy."
