我试图通过pecl安装APCu。安装顺利。但是，PHP无法加载APCu。
这是错误消息：
PHP警告：PHP启动：无法加载动态库'/usr/local/Cellar/php55/5.5.30/lib/php/extensions/no-debug-non-zts-20121212/apcu.so' - dlopen （/usr/local/Cellar/php55/5.5.30/lib/php/extensions/no-debug-non-zts-20121212/apcu.so,9）：找不到符号：_zend_signal_globals \ n引自：/ usr / local / Cellar / php55 / 5.5.30 / lib / php / extensions / no-debug-non-zts-20121212 / apcu.so \ n预期：平面命名空间\ n在/usr/local/Cellar/php55/5.5中。 30 / lib / php / extensions / no-debug-non-zts-20121212 / apcu.so in the Unknown on line 0
