我尝试在php:7.0-fpm-alpine上安装bz2扩展名（基于alpine 3.4）：
FROM php:7.0-fpm-alpine
RUN docker-php-ext-install bz2
但它失败了：

fetch http://dl-cdn.alpinelinux.org/alpine/v3.4/community/x86_64/APKINDEX.tar.gz

即使我尝试安装libbz2：apk add --update libbz2
知道如何安装此扩展程序吗？

@yosifkit：
在我看来，这是Alpine Linux中的包装错误。 libbz2包应该附带bzlib.h文件，就像Debian包那样：https://packages.debian.org/stretch/amd64/libbz2-dev/filelist。
