获取图像节点js的主色

我正在尝试获取计算机上图像的主色。在使用此代码之前，我安装了imagemagick和dominant-color。得到了undefined和000000的结果。

为什么会发生这种情况？我做错了什么？

var AWS = require('aws-sdk'),
fs = require('fs');
var express = require("express");
var app = express();
const resizeImg = require('resize-img');
var color = require('dominant-color'),
    imgPath = './Users/ADIBAR/Desktop/cloud/beach_life-normal.jpg';
color(imgPath,function(err,color){
    console.log(color);
})
color(imgPath,{format:'rgb'},function(err,color){
    console.log(color);
})
// For dev purposes only
AWS.config.update({ accessKeyId: '', secretAccessKey: '' });
var fileStream = fs.createReadStream('beach_life-normal.jpg');
fileStream.on('error', function (err) {
  if (err) { throw err; }
});  
fileStream.on('open', function () {
  var s3 = new AWS.S3();


resizeImg(fs.readFileSync('beach_life-normal.jpg'), {width: 128, height:128}).then(buf => {
    fs.writeFileSync('beach_life-normal-new.jpg', buf);
    //upload//
    s3.putObject({
      Bucket: 'adinoauploadefile',
      Key: 'beach_life-normal-new.jpg',
      Body: 'beach_life-normal-new.jpg'
    }, function (err) {
     if (err) { throw err; }
    });
  });  
});
