【问题描述】：

 @bot.command(pass_conetext = True)
async def info(ctx,  user: discord.Member):
    embed = discord.Embed(title = "Super Bot", description = "Thinking" , color = 0x00ff00)
    embed.add_field(name = "Name", value = user.name, inline = True)
    embed.add_field(name = "ID", value = user.id , inline = True)
    embed.add_field(name = "Status", value = user.status , inline = True)
    embed.add_field(name = "Highest Role", value = user.top_role , inline = True)
    embed.add_field(name = "Joined", value = user.joined_at , inline = True)
    embed.set_thumbnail(url = user.avatar_url)

每次我运行这段代码时都会返回这个错误，我不知道为什么

Ignoring exception in command info

    raise MissingRequiredArgument('{0.name} is a required argument that is missing.'.format(param))
discord.ext.commands.errors.MissingRequiredArgument: user is a required argument that is missing.

有人能解释一下原因吗，也许是一个解决方案

【问题讨论】：

你是如何调用命令的？你在 Discord 中输入什么来运行命令？
运行命令是不是
你拼错了pass_conetext，它应该是pass_context。这可能会影响传递给命令的参数
已经解决了这个谢谢

【解决方案1】：

运行该命令的人没有user 参数。

!info @user 而不是!info

【解决方案2】：

你可以把你的代码改成这样来拒绝错误：

@bot.command(pass_context= True)
async def info(ctx,  user: discord.Member=None):
    if user is None:
        user = ctx.message.author
    embed = discord.Embed(title = "Super Bot", description = "Thinking" , color = 0x00ff00)
    embed.add_field(name = "Name", value = user.name, inline = True)
    embed.add_field(name = "ID", value = user.id , inline = True)
    embed.add_field(name = "Status", value = user.status , inline = True)
    embed.add_field(name = "Highest Role", value = user.top_role , inline = True)
    embed.add_field(name = "Joined", value = user.joined_at , inline = True)
    embed.set_thumbnail(url = user.avatar_url)

基本上，如果用户什么都不是，它会给消息作者信息..
