I see what's going on...
first of all, don't call protractor a driver. Don't confuse others and most importantly yourself. Protractor is protractor, period.
second, when you do const driver= require("protractor") your driver variable is available in conf.js, but when you call it from the spec, it's not there, because it's a local variable, not global. As simple as that, this is why you get this error
Third, you don't need to define protractor because it is a global variable, and is available anywhere in your project anyways. The same with browser, element, $, $$ they all are available globally in your project.
Fourth, lets assume for whatever GOOD reason you still want to define something that will be globally available just do global.driver = require('protractor') as described here https://stackoverflow.com/a/31208642/9150146, and then you can call by typing the variable name driver
