是不是没装 mplayer ？（ #38 )

r00t8ug83 commented 9 years ago

@Hexcles 装了。

能不能试试看github上最新的版本？

不过原因我猜是歌曲列表空了，没装 mplayer 的话更容易出现，因为一首歌立即就“结束”了，一下就放完整个列表，来不及获取新歌曲。装了 mplayer 的话在网络不好或者其他状况下可能也会出现。

我实验一下。

@Hexcles 我的是github最新版本的。

@R00t8ug 最近一段时间做了不少调整，有可能不经意间影响了这个bug，能否再试试看？

这个异常是播放列表空了，但我仔细读了一遍源代码，每次获取下一首歌之前我们都检查了播放列表，如果是空的就去抓新的，但只尝试一次并且没有再检查。一般情况下是不会有问题的，但如果和豆瓣的连接质量较差，就可能导致抓不到播放列表。你的树莓派 ping www.douban.com 通畅么？

我会考虑对这个地方处理一下，但由于获取列表已经是相对较快的 API 了，出错机率也很低，如果这儿都失败的话后面其他地方可能也要卡很久甚至出错。最好情况就是让它 fail loudly and gracefully 了。
