Angular 2 - TypeError undefined不是Array的函數

我的Angular 2項目是使用angular-cli 1.0.0-beta.30版本創建的。我正在使用ngx-charts版本4.1.2庫。條形圖組件工作正常，但是當我添加折線圖時，運行應用程序時會引發TypeError異常。在Chrome版本運行時，誤差是「包含」在[行chart.component.ts] [1]的源文件240線功能38.折線圖顯示正確的FirefoxAngular 2 - TypeError undefined不是Array的函數

if (!values.includes(d.name)) { 
    values.push(d.name); 
}

我如何使數組包含我的應用程序已知的函數？

在我tsconfig.json文件我有

"lib": ["es6", "dom"],

我的package.json文件包含以下

    } 
}

我polyfills.ts文件包含

import 'core-js/es6/array';

我已經通過ngx圖表演示和其他例子看，但我不明白爲什麼我收到錯誤。

謝謝

我發現了這個問題。該polyfills.ts文件包含

import 'core-js/es6/array';

我需要

import 'core-js/es7/array';

添加到文件中。

我在想這是由於我公司PC上安裝的Chrome版本。這是版本38. Array.includes的developer.mozilla.org頁指出支持Chrome版本是47版。
