swoole定时器报错 \Event::rshutdown(): Event::wait() in shutdown function is deprecated

1. 运行环境#

php7.4
swoole4.8.5

2). 当前系统#

centos7

2. 问题描述？#

初次用 swoole，规规矩矩的按照文档写，报了个携程相关的错误，搜出来的答案都是这么说的定时器会自动创建携程，wait 在处理携程的时候就会包这种错，严格来说不算报错，毕竟不影响运行，但是怎么处理呢就知道了

<?php
use Swoole\Process;
use Swoole\Timer;

swoole_async_set([
    'enable_coroutine' => false,
  ]);
for ($n = 1; $n <= 3; $n++) {
    $process = new Process(function () use ($n) {
        $timer = Timer::tick(2000, function(){
            echo time();
        });
    });
    $process->start();
}
for ($n = 3; $n--;) {
    $status = Process::wait(true);
    echo "Recycled #{$status['pid']}, code={$status['code']}, signal={$status['signal']}" . PHP_EOL;
}
echo 'Parent #' . getmypid() . ' exit' . PHP_EOL;
