Question

我正在尝试为我的不和谐机器人制作一个经济系统。我在 youtube 上学习了一个教程，唯一改变的是我在 cogs 中添加了它。

错误：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NameError: name 'open_account' is not defined

追溯：

Traceback (most recent call last):
  File "C:\Users\liene\AppData\Local\Programs\Python\Python38\lib\site-packages\discord\ext\commands\bot.py", line 965, in invoke
    await ctx.command.invoke(ctx)

    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: NameError: name 'open_account' is not defined

错误消息告诉我错误所在的位置：

class Economy(commands.Cog):
    def __init__(self, client):
        self.client = client

    @commands.command()
    async def balance(self, ctx):
        await open_account(ctx.author)
        user = ctx.author
        users = await get_bank_data()

        wallet_amt = users[str(user.id)]["wallet"] = 0
        bank_amt = users[str(user.id)]["bank"] = 0

        em = discord.Embed(title=f"{ctx.author.name}'s balance", colour = discord.Color.green())
        em.add_field(name = "Wallet balance", value = wallet_amt)
        em.add_field(name = "Bank balance", value = bank_amt)

        await ctx.send(embed=em)

Answer 1

您的 open_account 函数是 Economy 类的方法。要从同一类的不同方法调用它，您必须执行 await self.open_account(ctx.author)。

discord.ext.commands.errors.CommandInvokeError：命令引发异常：NameError：未定义名称“open_account”
