Question

所以我有这个代码作为我的前缀。我没有问题。它工作正常，但是每当我向我的机器人发送消息时，都会出现此错误。反正有没有忽略或解决它？谢谢

with open("prefix.json") as f:
    prefixes = json.load(f)
    default_prefix = "?"

def prefix(client, message):
    id = message.guild.id
    return prefixes.get(id, default_prefix)

client = commands.Bot(command_prefix=prefix)

@client.command(name="Prefix", aliases=["prefix", "setprefix"])
@commands.has_permissions(manage_guild=True)
async def _prefix(ctx, new_prefix):
    msg = ctx.message
    prefixes[msg.guild.id] = new_prefix
    with open("prefix.json", "w") as f:
        json.dump(prefixes, f, indent=4)

Error:

对于所有DM，

product将是original_price（因为它们没有被发送给公会）。您应该在function sortAscendingPrice(a, b) { return a.original_price - b.original_price; } function sortDescendingPrice(a, b) { return b.original_price - a.original_price; } function sortAscendingProduct(a, b) { return a.product - b.product; } function sortDescendingProduct(a, b) { return b.product - a.product; } const data = [ { product: 1, price: [ {id: 1, original_price: 18}, {id: 2, original_price: 10} ] }, { product: 2, price: [ {id: 1, original_price: 12}, {id: 2, original_price: 15}, {id:3, original_price: 5} ] } ]; const sortedData = data .map(el => { return { product: el.product, price: el.price.sort(sortAscendingPrice) }; }) .sort(sortDescendingProduct);函数中为此添加一个大小写。

message.guild

命令工作正常，但是每当我使机器人僵尸时我都会出错。 [discord.py]
