我安装了node.js后，mpegts.js-master文件夹放在桌面，用cmd输入以下指令： npm install --save mpegts.js，出现 npm install ，出现 npm install -g webpack-cli ，出现 npm run build，出现 这个安装顺序有问题吗？还有想问一下

Getting Started

<script src="mpegts.js"></script>
<video id="videoElement"></video>
<script>
    if (mpegts.getFeatureList().mseLivePlayback) {
        var videoElement = document.getElementById('videoElement');
        var player = mpegts.createPlayer({
            type: 'mse',  // could also be mpegts, m2ts, flv
            isLive: true,
            url: 'http://example.com/live/livestream.ts'
        });
        player.attachMediaElement(videoElement);
        player.load();
        player.play();
    }
</script>
