[Resolved] Cannot find Arduino port in Serial In or Serial Out nodes

General

Could it be still hanging onto the port.

A sure fire way is to reboot PC & try again.

Failing that, perhaps there was an issue compiling the serial port code for Windows 10 when you installed node-red or a node that installs serial?

Did / do you have windows-build-tools installed?

npm install --global windows-build-tools

if not - then you might need to install that then install serial port again

see this similar thread Error while lauching Node-Red: "It looks like serialport didn't compile properly. This is a common problem and its fix is well documented here https://github.com/voodootikigod/node-serialport#to-install" - #3 by Jasurf
