angular - 类型错误 : Buffer is not a constructor using Angular Material Table Exporter

Question

我从控制台(firefox)得到的错误

我希望能够使用 mat-table-exporter 导出我的 Angular 应用程序的表( Material 表):https://www.npmjs.com/package/mat-table-exporter .

这是我要重现的堆栈:https://stackblitz.com/edit/mte-demo?file=src%2Fapp%2Fapp.module.ts

我的 HTML 模板:

<button mat-raised-button (click)="exporter.exportTable('xlsx', {fileName:'test', sheet: 'sheet_name', Props: {Author: 'Talha'}})">Excel</button>
<table mat-table [dataSource]="serverArray" multiTemplateDataRows matTableExporter #exporter="matTableExporter">
   .
   .
   .
</table>

Answer 1

我的 index.html 文件中有一个脚本:

<script>
    var global = global || window;
    // var Buffer = Buffer || [];
    var process = process || {
      env: { DEBUG: undefined },
      version: []
    };
</script>

注释带有“Buffer”变量的行解决了我的问题。
