着急的盆友可以直接看下面我的解决办法（大家项目不同，报错原因也可能不同，但是可以试试这个思路），不着急的童鞋可以看看跟我的报错是否一样。
最近项目中才接触m3u8格式的文件，其实相当于是对视频文件记录地址、时长等信息的索引文件，在网上查询说是用videojs来播放，于是下载、引入了videojs，这里不详细描述，可参考网址： # 使用videojs播放 .m3u8格式文件
按照上文链接中的方法，在之前一个demo项目中用的很顺利，正常播放m3u8文件也没报错。但是今天我又新起了一个项目，把之前demo的代码拿过来，发现一样的m3u8播放不了了，报错信息：VIDEOJS: ERROR: (CODE:3 MEDIA_ERR_DECODE) Playback cannot continue. No available working or supported playlists.
详细报错信息：（太长不看版）

最后发现罪魁祸首是引入了mock： import ‘./mock’;
把这一行注释掉就可以了：
原理我还没搞明白，理论上来说引入了没有使用应该是没有影响的，但是我这确实报错了。
大家不同的项目引入的组件不同，如果遇到同款问题，建议把可疑的引入先注释掉看看情况。
因为这个报错，各种中网外网查咋回事，浪费了我一天时间。。。
