discord.py on_member_join 不起作用@bot.event

Question

Below is my code for a discord bot. I am trying to get it to change the server name to the amount of members in the server. I looked at this example but it did not work. Can anyone help? I do not receive any errors, and my output is also below. When I try and add the @bot.event for on_member_join, it does not seem to even get there.

Output

bot.run(TOKEN)

Answer 1

You need to add the event decorator :

@bot.event
async def on_member_join(member):
    ...

Answer 2

You are creating both a Client and a Bot , you should only use one or the other.

Either change all of your @client decorators to @bot decorators or change your client line to client = Bot(...) and get rid of client = discord.Client()

Answer 3

我更新到 v 1.5 并修复了它！
