Как устранить тип ошибки диаграммы свойств не существует по типу "typeof Google" в диаграмме столбца Google

Я пытаюсь создать диаграмму столбцов Google в angular2 и typescript. Но я получил диаграммы свойств ошибки, которых нет в типе typeof google в диаграммах столбцов google. Когда я запускаю команду npm start, то она показывает ошибку. Здесь мой код

google.charts.load('44', {packages: ['corechart', 'bar']});
google.charts.setOnLoadCallback(drawColColors);

function drawColColors() {
      var data = new google.visualization.DataTable();
      data.addColumn('timeofday', 'Time of Day');
      data.addColumn('number', 'Motivation Level');
      data.addColumn('number', 'Energy Level');

      data.addRows([
            [{v: [8, 0, 0], f: '8 am'}, 10, 7,],
            [{v: [9, 0, 0], f: '9 am'}, 6, 8],
            [{v: [10, 0, 0], f:'10 am'}, 3, 9],
            [{v: [11, 0, 0], f: '11 am'}, 4, 2.25],
            [{v: [10, 0, 0], f:'10 am'}, 3, 8],
            [{v: [11, 0, 0], f: '11 am'}, 4, 6],
      ]);

      var options = {
            colors: ['#9575cd', '#33ac71','#FF0000','#FFFF00'],
            legend: 'none',
            bar: {groupWidth: "80%"},
            hAxis: {
                 textPosition: 'none',
                  gridlineColor: '#fff',
            },
            vAxis: {
             //baselineColor: '#fff',
             gridlineColor: '#fff',
             textPosition: 'none'

            }
      };

var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
          chart.draw(data, options);
        } 

Я получил следующую ошибку. Пожалуйста, помогите мне, как решить.
