Node.JS Cannot find module message unhelpful

[simpljs]

Hi I have the following interaction, as you see the package ID is not found, immediately after being installed. This does not make any sense to me.
Why is there not more info in the error message?

PS C:\opnsrc\ndEnv\smartPower> npm install -g tplink-smarthome-api

the hello2.js code is:

const { Client } = require('tplink-smarthome-api');


const client = new Client();


client.getDevice({ host: '10.0.0.60' }).then((device) => {

  device.getSysInfo().then(console.log);

});
