在node.js中读取excel文件时出现FileReader错误

我正在尝试使用模块“FileReader”和“xlsx”读取发送到服务器的excel文件

var file = body.file;

var xlsx = require('xlsx');
var FileReader = require('FileReader');

var reader = new FileReader();
reader.onload = function (e) {
   var data = new Uint8Array(e.target.result);
   var workbook = xlsx.read(data, { type: 'array' });
};
reader.readAsArrayBuffer(file);

但我在运行它时会出现以下错误：

Error: Cannot find module 'bufferjs/concat'

我已经在node.js系统中安装了'bufferjs'。

我想是因为我使用了新的keyworkd for FileReader，所以出现了这个错误
