将Gulp Uglify与js数组一起使用时出现Javascript错误

我在一口气运行uglify时遇到以下错误。在文档头的脚本中调用相同的代码时未获得错误。请告知如何修复错误

终端错误：

Uglify显然不懂

playerVars:playerVars

的ES6速记

playerVars

我想你可以通过安装来解决这个问题。或者干脆用传统的语法代替速记。

这与playerVars的降格有关吗？Use const playerVars={“自动播放”：1，“控件”：0，“相关”：0，“显示信息”：0，“循环”：1，“自动播放”：1}；

  window.onYouTubeIframeAPIReady = function() {
      playerVars = { 'autoplay': 1, 'controls': 0, 'rel': 0, 'showinfo': 0, 'loop': 1, 'modestbranding': 1 };

      return new YT.Player('youtubeVideoPlayer', {
        height: playerHeight,
        width: playerWidth,
        videoId: player.data('video-id'),
        playerVars,
        events: {
            onReady: function(e) {
              frame = holder.find('iframe');
              e.target.mute();
              resizeHandler();
            }
          }
      });
  }
