Solution 1:

As this GitHub issue answer states, you cannot use require itself inside a function node, but you can add external modules to the sandbox used to run functions. You would do this setting functionGlobalContext inside your settings.js file like the following:

functionGlobalContext: {
    tzModule:require('moment-timezone')
}

The module can then be referenced by using the following code:

var moment = global.get('tzModule');

Check out the Node-RED documentation on global-context for full details.

Solution 2:

Settings file:/Users/aiquantong/.node-red/settings

Please do configure in this file, it will be working.
