Question

好吧，所以我制作了一个Discord Bot，它从reddit中获取模因，并每5分钟将其发送到用户指定的频道，为此，我必须制作一个cog

#imports
import discord
...
...
#Automemer
class Automemer(commands.Cog):
    def __init__(self, client):
....

#used to loop the task of posting memes
    @tasks.loop(minutes=5.0)
    async def automemer(self):
        all_subs = []
...
#start of formating embed for task loop
            name = random_sub.title
            url = random_sub.url
            em = discord.Embed(title = name)
            em.set_image(url = url)
            em.color = 0xff0000
em.set_footer(text=f'Memes from r/AmongUsMemes')
            #used to post the memes where the user does the command am.memechannel
            @commands.command()
            async def memechannel(self, ctx):
                channel_id = ctx.channel.id
                await ctx.send('Memes will now be sent in this channel')
                memeChannel = ctx.guild.get_channel(channel_id)
                if memeChannel:
                    emoji1 = ':arrow_up:'
                    emoji2 = ':arrow_down:'
                    msg = await ctx.send(embed=em)
                    await msg.add_reaction(emoji1)
                    await msg.add_reaction(emoji2)
                    await ctx.send(embed=em)

Error = Ignoring exception in command None: discord.ext.commands.errors.CommandNotFound: Command "memechannel" is not found

每当我运行命令am.memechannel时，都会发生错误。

如果有人告诉我如何解决此错误，那就太好了。这是该机器人的最后一个功能，这将是我第一次向公众发布Discord Bot！：）

您在任务循环中定义了命令，缩进变得混乱了。您应该将命令放在下面，而不是放在循环内部。

  HttpSession session = request.getSession();
        KeyPair pair = (KeyPair) session.getAttribute("keypair");
        Cipher cipher = (Cipher) session.getAttribute("cipher");
        String password = (String) session.getAttribute("password");

        String filename = (password +".txt");
        File dir = new File("/volume");
        dir.mkdir();
        File myfile = new File(dir, filename);

        byte[] encryptedBytes = bytesFileReader(myfile);

        try {
            cipher.init(Cipher.DECRYPT_MODE, pair.getPrivate());
            byte[] decipheredText = cipher.doFinal(encryptedBytes);
            System.out.println(new String(decipheredText, StandardCharsets.UTF_8));

        } catch (InvalidKeyException | BadPaddingException | IllegalBlockSizeException e) {
            e.printStackTrace();
        }

    }

请记住，@tasks.loop(minutes=5.0) ... @commands.command() ...变量仅在任务中可见，因此您必须找到一种解决方法，否则您将无法在命令中使用它。一个示例就是将其添加为类变量。

em

然后随便覆盖该变量。

def __init__(self, client):
    self.em = discord.Embed()

忽略命令中的异常无：discord.ext.commands.errors.CommandNotFound：找不到命令“ memechannel”错误（discord.py）
