您好，这新版的扩展ext-async似乎与swoole4.5.1版本不匹配

[YunMengs]

我的swoole扩展版本是4.5.1 然后今天我拉取了ext-async主分支代码，进行编译安装，过程中没有出现任何问题，我运行PHP时会报错： PHP Fatal error: PHP Startup: Ext version (40501) does not match the Swoole version (40500) in Unknown on line 0 这似乎是我的ext-async扩展版本高于swoole版本（官网swoole最新版本就是4.5.1），但是尝试下载旧版本ext-async甚至连编译都无法通过 #error "Ext version does not match the Swoole version" 似乎我的两个扩展版本是匹配的，但是为什么会报错呢？

My swoole extension version is 4.5.1. Today, I pulled the ext-async master branch code and compiled and installed it. There were no problems during the process. I will get an error when running PHP: PHP Fatal error: PHP Startup: Ext version (40501) does not match the Swoole version (40500) in Unknown on line 0 This seems to be that my ext-async extension version is higher than the swoole version (the latest version of the official website swoole is 4.5.1), but trying to download the old version ext-async even the compilation fails #error "Ext version does not match the Swoole version" It seems that my two extended versions match, but why is an error reported?
