telebot 在使用 multiprocessing [exe 文件] 时出现错误 409

Error 409 occurred in telebot when using multiprocessing [exe file]

我想启动另一个进程,它会启动,如果我写电报机器人“启动”。但就在这发生之后错误:

2022-04-11 11:16:13,602 (__init__.py:688 Thread-1) 
ERROR - TeleBot: "A request to the Telegram API was unsuccessful. Error code: 409. 
Description: Conflict: terminated by other getUpdates request;
make sure that only one bot instance is running"

我运行同时只有一个机器人,已经检查过了。我发现,当程序试图启动一个新进程时会发生错误。有谁能帮帮我吗?

from time import sleep
from datetime import datetime, timedelta
import telebot
from telebot import types
from threading import Thread
import multiprocessing


def collecting(a):
    while True:
        print(a)
        sleep(3)

if __name__=='__main__':

    bot = telebot.TeleBot(token)

    workers = []

    def listen():
        @bot.message_handler(content_types='text')
        def get_text(message):
            id = message.chat.id
            mes = message.text
            if mes=='start':
                bot.send_message(id, 'okey')
                workers.append([str(datetime.now())])
            else:
                bot.send_message(id, mes)
        bot.polling()

    Thread(target=listen).start()
    while True:
        sleep(1)
        x = workers[:]
        for i in range(len(x)):
            multiprocessing.Process(target=collecting, args=(x[i],)).start()
            del workers[i]

UPD: 忘了说了,这个错误只发生在我创建exe文件和运行这段代码像exe程序的时候。这就是我创建 exe 文件的方式:

pyinstaller --hidden-import=pkg_resources.py2_warn --onefile Program.py

已解决,我忘了添加:

from multiprocessing import freeze_support

然后在if__name__=="__main__":之后还需要写freeze_support().
