为什么swoole部分的的php8添加了pecl后提示未找到pecl

参考dev,ln -s 了pecl到pecl8还是pecl8 not found
swoole目录下的dockerfile应该如何正确添加相关extension

Start by reading the Dockerfile in the swoole directory and compare its PHP 8 setup with the referenced dev configuration. Reproduce the `pecl8 not found` message, then verify that the image can add the required extension successfully and that the resulting PECL command is available.
