好，所以我正在使用一个较旧的机器人，并试图重写我的自定义帮助命令，以减少手动操作。但是，我不确定如何使它按预期工作。
我的问题如下：
I can't send embeds异常作为响应有人可以帮我解决这个问题吗？
这是我自定义的帮助命令。
@commands.command(name="help", aliases=["Help", "H", "h"])
@commands.has_permissions(add_reactions=True, embed_links=True)
async def help(self, ctx, *cog):
"""Gets all cogs and commands.
Alt : h, H, Help
Usage : [h]elp <cog or command>"""
try:
if not cog:
"""Cog listing. What more?"""
embed = discord.Embed(color=discord.Color.dark_gold(),
title='Cog Listing and Uncatergorized Commands',
description=f'Use `{prefix}help <cog>` to find out more about them!\nNote: The Cog Name Must Be in Title Case, Just Like this Sentence.',
timestamp=ctx.message.created_at)
embed.set_author(name=self.client.user.name, icon_url=self.client.user.avatar_url)
cogs_desc = ''
for x in self.client.cogs:
cogs_desc += ('{} - {}'.format(x, self.client.cogs[x].__doc__) + '\n')
embed.add_field(name='Cogs', value=cogs_desc[0:len(cogs_desc) - 1], inline=False)
cmds_desc = ''
for y in self.client.walk_commands():
if not y.cog_name and not y.hidden:
cmds_desc += ('{} - {}'.format(y.name, y.help) + '\n')
embed.add_field(name='Uncatergorized Commands', value=cmds_desc[0:len(cmds_desc) - 1], inline=False)
await ctx.send('', embed=embed)
else:
"""Helps me remind you if you pass too many args."""
if len(cog) > 1:
embed = discord.Embed(color=discord.Color.dark_red(), timestamp=ctx.message.created_at)
embed.set_author(name="Command Failed", icon_url=self.client.user.avatar_url)
embed.add_field(name="Error", value="Too many cogs", inline=False)
await ctx.send('', embed=embed)
else:
"""Command listing within a cog."""
found = False
for x in self.client.cogs:
for y in cog:
if x == y:
embed = discord.Embed(color=discord.Color.dark_gold(), timestamp=ctx.message.created_at, title=cog[0] + ' Command Listing', description=self.client.cogs[cog[0]].__doc__)
for c in self.client.get_cog(y).get_commands():
if not c.hidden:
embed.add_field(name=c.name, value=c.help, inline=False)
found = True
if not found:
"""Reminds you if that cog doesn't exist."""
embed = discord.Embed(color=discord.Color.dark_red(), timestamp=ctx.message.created_at)
embed.set_author(name="Command Failed", icon_url=self.client.user.avatar_url)
embed.add_field(name="Error", value='Can not use "' + cog[0] + '"?', inline=False)
else:
await ctx.send('', embed=embed)
except:
await ctx.send("I can't send embeds.")
如果有帮助，我正在使用discord.py-rewrite。

由于无数问题，我放弃了上面的代码。并去了下面的代码。我仍然希望它不那么手动，但目前此文章已发布。

但是，是的，如果有人知道如何做到这一点，那么可以从齿轮读取命令，而不是手动将命令键入到help命令的响应中，那么任何提示将非常有帮助。
