ctx = player.ctx AttributeError：“Player”对象没有属性“ctx”

Question

我在做音乐机器人，但我得到了

AttributeError: 'Player' object has no attribute 'ctx'

当我做>>play音乐时，另一种音乐正在播放(应该是为了排队)

全误差

Bot Online

如果我是对的，应该是一个版本问题。您的代码没有什么问题。，直到我重新安装了小波，我才有这个值，所以我更希望这是一个版本问题，我不知道哪个版本有这个ctx值，但是如果我找到正确的版本，我会回答您！

编辑

有player.ctx的版本是1.2.5，我不确定1.3.0是否还有player.ctx，但我做的是1.2.5，因为它是一个更稳定的版本(对我来说)。

安装

python3 -m pip install wavelink==1.2.5，python -m pip install wavelink==1.2.5或py -m pip install wavelink==1.2.5，取决于您的机器。您也可以尝试1.2.3版本。

重要

也可能是，bot在调用中停留时间太长，和小波无法从它中提取ctx。
