Uncaught TypeError: d3.pack(...).sort is not a function

I am new to Javascript and D3.js and I am currently trying to build a bubble chart in d3.js using an example provided here https://jrue.github.io/coding/2014/exercises/basicbubblepackchart/ and modifying it according to my assignment. I know that the example above was written in a previous version of d3, and I am using version v4 where syntax has slightly changed,however I am getting a following error when running a program:

Uncaught TypeError: d3.pack(...).sort is not a function

var diameter = 500, //max size of the bubbles
color    = d3.scaleOrdinal(d3.schemeCategory10); //color category

var bubble = d3.pack()
.sort()
.size([diameter, diameter])
.padding(1.5);

var svg = d3.select("body")
.append("svg")
.attr("width", diameter)
.attr("height", diameter)
.attr("class", "bubble");

d3.csv("teams.csv", function(error, data){

data = data.map(function(d){ d.value = +d["Amount"]; return d; });

var nodes = bubble.nodes({children:data}).filter(function(d) { return !d.children; });

//setup the chart
var bubbles = svg.append("g")
    .attr("transform", "translate(0,0)")
    .selectAll(".bubble")
    .data(nodes)
    .enter();

bubbles.append("circle")
    .attr("r", function(d){ return d.r; })
    .attr("cx", function(d){ return d.x; })
    .attr("cy", function(d){ return d.y; })
    .style("fill", function(d) { return color(d.value); });

bubbles.append("text")
    .attr("x", function(d){ return d.x; })
    .attr("y", function(d){ return d.y + 5; })
    .attr("text-anchor", "middle")
    .text(function(d){ return d["Team"]; })
    .style({
        "fill":"black", 
        "font-family":"Helvetica Neue, Helvetica, Arial, san-serif",
        "font-size": "12px"
    });

What is the problem here?

Be sure to use the same version of d3 as the author in the example (it looks like you're good by the syntax). Also, it's 'd3.layout.pack().sort(null)' :)
