Answer 1

配置文件php.ini，extension_dir设置错误。
/usr/local/Cellar/php54/5.4.33/lib/php/extensions/no-debug-non-zts-20100525/该目录下并没有memcache.so等文件，在其他目录里面

Answer 2

这种情况主要还是扩展目录指定的问题，如果你确定装了这些扩展 你可以查找这些扩展的目录然后指定一下

Answer 3

终端 php -i |grep mongo查看你的扩展是否安装成功。
如果没有 需要下载 扩展并编译安装 安装完成后需要在php.ini中添加模块

Answer 4

可能1：命令行下php.ini没有自动加载,可以手动指定

php  -c  /etc/php.ini a.php

可能2： 命令行下默认执行的php与web所执行的不一致，查看phpinfo中的php路径，与命令行中的是否一致，不一致的话要改成一致的，或者给两个版本都安装上对于的扩展

which php #看路径

Answer 5

推荐使用brew安装，省去很多麻烦
