无法在PHP5.6-apache容器中安装memcached包

我正在尝试让mamcache工作.使用https://hub.docker.com/_/php/中的示例(PECL扩展).

我的dockerfile简单做了下一步:

 FROM php:5.6-apache

 RUN apt-get update && apt-get install -y libmemcached-dev \
 && pecl install memcached \ 
 && docker-php-ext-enable memcached

但最后我得到了下一个:

checking for zlib location... configure: error: memcached support requires ZLIB. Use --with-zlib-dir= to specify the prefix where ZLIB headers and library are located
ERROR: `/tmp/pear/temp/memcached/configure --with-php-config=/usr/local/bin/php-config --with-libmemcached-dir=no' failed
error: /usr/local/lib/php/extensions/no-debug-non-zts-20131226/memcached does not exist

usage: /usr/local/bin/docker-php-ext-enable [options] module-name [module-name ...]
   ie: /usr/local/bin/docker-php-ext-enable gd mysqli
       /usr/local/bin/docker-php-ext-enable pdo pdo_mysql
       /usr/local/bin/docker-php-ext-enable --ini-name 0-apc.ini apcu apc

Possible values for module-name:
opcache.so

我做错了什么？

您需要安装zlib开发包.添加zlib1g-dev(不是100%确定包名称 - 如果它不起作用则注释)到apt-get install命令.
