我的代码：

    #Ban command
    @bot.command()
    async def ban(ctx, member : discord.Member, *, reason='nothing'):
        #to check if user has permissions
        if has_permissions(ban_members=True):
            #to not let admins ban each other
            check = False
            for i in member.roles:
                if i in ctx.author.roles[1:]:
                    check = True
    
            if(check):
                await ctx.send('❌ Cant ban admins/moderators.')
            else:
                
                await member.ban(reason=reason)
                await ctx.send(f'✓ {member} has been banned')
        else:
            await ctx.send(' you dont have that permission')

问题是没有权限的用户如果使用该命令不会打印：you don't have that permission，我得到一个错误。

你可以试试ctx.author.guild_permissions。或者在@bot.command()之后使用discord.py的@bot.has_permissions(ban_members=True)方法

    @bot.command()
    async def ban(ctx, member : discord.Member, *, reason='nothing'):
        #to check if user has permissions
        if ctx.author.guild_permissions.ban_members:
            #to not let admins ban each other
            check = False
            for i in member.roles:
                if i in ctx.author.roles[1:]:
                    check = True
    
            if(check):
                await ctx.send('❌ Cant ban admins/moderators.')
            else:
                
                await member.ban(reason=reason)
                await ctx.send(f'✓ {member} has been banned')
        else:
            await ctx.send(' you dont have that permission')
