不和谐的关键错误。派

Question

@client.command(description="Pauses the current playing track. Can be resumed with `!resume`.", 
brief="Pauses current track.",aliases=['PAUSE'])
async def pause(ctx):
    guild_id = ctx.message.guild.id
    players[guild_id].pause()

@client.command(description="Resumes the current playing track. Can only be used if current track has 
been paused.",
    brief="Resumes current track.",
    aliases=['RESUME','continue','CONTINUE'])
async def resume(ctx):
    guild_id = ctx.message.guild.id
    players[guild_id].resume()

@client.command(description="Stops the current playing track.",
     brief="Stops current track.",
     aliases=['STOP'])
async def stop(ctx):
    guild_id = ctx.message.guild.id
    players[guild_id].stop()

当我尝试使用pause、stop和resume命令时，它会给出keyrerror。触发该错误的全部代码都在上面。错误是这样的：

忽略命令stop:Traceback（最近一次调用last）中的异常：文件“C:\Users\emirs\PycharmProjects\discordmasterbot\venv\lib\site packages\discord\ext\commands\core.py”，第83行，在wrapped ret=await coro（*args，**kwargs）文件“C:/Users/emirs/PycharmProjects/discordmasterbot/MASTERBOT.py”，第163行，停止玩家[guild\u id]。stop（）键错误：708748879079932016

还有另一种类型的错误：

回溯（最近一次调用）：文件“C:\Users\emirs\PycharmProjects\discordmasterbot\venv\lib\site packages\discord\ext\commands\bot.py”，第892行，调用等待ctx。命令调用（ctx）文件“C:\Users\emirs\PycharmProjects\discordmasterbot\venv\lib\site packages\discord\ext\commands\core.py”，第797行，在调用等待注入（*ctx.args，**ctx.kwargs）文件“C:\Users\emirs\PycharmProjects\discordmasterbot\venv\lib\site packages\discord\ext\commands\core.py”，第92行，在命令调用程序（exc）中来自exc的不和谐。外部命令。错误。CommandInvokeError:命令引发异常：KeyError:708748879079932016

Answer 1

KeyError表示找不到此对象的键。在这种情况下，玩家中不存在公会ID708748879079932016。

尝试在这里添加一个尝试/除块来捕获这些内容。
