Memcache扩展未加载！要配置池，必须加载它！MAMP PRO升级到PHP7.2

我最近将MAMP PRO中的PHP版本从PHP7.1.19切换到PHP7.2.20。我目前使用Symfony 3.4。但是，Symfony现在一直抱怨我的memcache扩展丢失：

我读到这可能是因为7.2不再支持memcache？我已经尝试了很多方法来安装memcache for PHP7.2，但都没有成功

pecl install memcache

但是，安装失败，并以以下行结束（致命错误：“zend_config.h”文件未找到）：

我还尝试将memcache.so添加到php.ini中。但我不确定从哪里获得PHP7.2的正确memcache.so文件

我已将extension=memcache.so添加到我的php.ini文件MAMP PRO文件编辑模板<7.2.20

请注意，此错误与memcache有关，而与memcached无关。我还没有找到任何关于我的memcache错误的StackOverflow解决方案
