node-serialport: TypeError: SerialPort.parsers.ReadLine is not a function

SerialPort version: 4.x NodeJS Version: 4.5 Operating System and Hardware: raspian jesse lite & pi zero Are you using Electron/Atom/NwJS?: No

(Run node -v && npm -v && python --version to get version numbers)

Summary of Problem

Reading the serial port without a parser works just fine; but, when running the example code for the readline parser I receive this error:

var parser = SerialPort.parsers.ReadLine();
                                ^
TypeError: SerialPort.parsers.ReadLine is not a function

Expected Behavior

That the example code for the readline parser would run:

var SerialPort = require('serialport');
var ReadLine = SerialPort.parsers.ReadLine;
var port = new SerialPort('/dev/serial0');
var parser = SerialPort.parsers.ReadLine();
port.pipe(parser);
parser.on('data', console.log);

Any idea what could be causing this error? I have installed the code using

npm install serialport

and

npm install serialport --build-from-source

I installed node two different ways with the same results… self compiled and downloading the arm6 binaries.
