错误消息未定义（Discord，Python）

Question

我只需要一件事-您可以帮助重写此简单代码（并立即给出现成的答案）。这段代码对我来说很重要，但是我不了解很多事情，我只能为您希望

我尽力了

# welcome-bot
## this bot will send a welcome message and assign a role

# import all necessary commands and libraries
import discord
import asyncio

client=discord.Client()

@client.event
async def on_ready():
    print('logged in as')
    print(client.user.name)
    print(client.user.id)
    print('-----')

newUserMessage = """ # customise this to the message you want to send new users
You
can
put
your
multiline
message
here!
"""

@client.event
async def on_member_join(member):
    print("Recognised that a member called " + member.name + " joined")
    await message.channel.send(member, newUserMessage)
    print("Sent message to " + member.name)

    # give member the steam role here
    ## to do this the bot must have 'Manage Roles' permission on server, and role to add must be lower than bot's top role
    role = discord.utils.get(member.server.roles, name="name-of-your-role")
    await message.channel.sends(member, role)
    print("Added role '" + role.name + "' to " + member.name)

client.run('here token, i knew') 

NameError：未定义名称“消息”
