Hi,

I uninstalled node-red usingsudo npm uninstall -g node-red and reinstalled it using sudo npm install -g --unsafe-perm node-red. I am getting following error while installing.

node-pre-gyp ERR! Completion callback never invoked! 
node-pre-gyp ERR! System Linux 4.15.0-34-generic

What is the reason for this issue?

Not sure - but it is an optional dependancy so not the end of the world.

Or you could try following the update instructions - https://github.com/nodejs/node-gyp/wiki/Updating-npm's-bundled-node-gyp

(shouldn't generally be necessary so what platform / OS are you running on ? )
