根据官方docker镜像文档：

"E: Package 'php-XXX' has no installation candidate"

从docker-library/php#542开始，此镜像阻止安装Debian的PHP包。在docker-library/php#551 (comment)中有一些关于此更改的讨论，但要点是在此镜像中安装Debian的PHP包会导致一个镜像中存在两个冲突的PHP安装，这几乎肯定不是预期的结果。

对于那些被此更改破坏并寻找临时解决方法的人，将以下简单行添加到您的Dockerfile中将删除该阻止（强烈警告：这将允许安装第二个PHP安装，除非您确实知道自己在做什么，否则绝不是您想要的）：

RUN rm /etc/apt/preferences.d/no-debian-php

此错误的正确解决方法是使用FROM debian:XXX并直接安装Debian的PHP包，或者使用docker-php-ext-install、pecl和/或phpize来安装必要的附加扩展和实用程序。

解决方案

Dockerfile:

FROM php:7.1

RUN apt update && \
    apt upgrade && \
    apt install -y libmagickwand-dev --no-install-recommends && \
    pecl install imagick && docker-php-ext-enable imagick && \
    rm -rf /var/lib/apt/lists/*

使用以下方法构建：

$ sudo docker build -t exadra37/php-imagick:7.1 .

@Exadra37的答案是正确的。但请注意，您在安装PHP扩展后也可以删除一些APT软件包（它们仅用于编译/安装扩展，而不是使用它 - 您将节省近200 MB）：

FROM php:7.1

RUN apt-get update && \
    apt-get install -y libmagickwand-dev && \
    pecl install imagick && \
    docker-php-ext-enable imagick && \
    apt-get remove --purge -y automake autotools-dev bzip2-doc fontconfig gir1.2-freedesktop gir1.2-gdkpixbuf-2.0 gir1.2-glib-2.0 gir1.2-rsvg-2.0 icu-devtools javascript-common libblkid-dev libbz2-dev libcairo-gobject2 libcairo-script-interpreter2 libcairo2 libcairo2-dev libcroco3 libdatrie1 libdjvulibre-dev libdjvulibre-text libdjvulibre21 libelf1 libexif-dev libexif-doc libexif12 libexpat1-dev libffi-dev libfontconfig1-dev libfreetype6-dev libfribidi0 libgdk-pixbuf2.0-0 libgdk-pixbuf2.0-bin libgdk-pixbuf2.0-common libgdk-pixbuf2.0-dev libgirepository-1.0-1 libglib2.0-bin libglib2.0-data libglib2.0-dev libglib2.0-dev-bin libgraphite2-3 libharfbuzz0b libice-dev libice6 libicu-dev libilmbase-dev libilmbase23 libjbig-dev libjpeg-dev libjpeg62-turbo-dev libjs-jquery libjxr-tools libjxr0 liblcms2-dev liblqr-1-0-dev libltdl-dev liblzma-dev liblzo2-2 libmagickcore-6-arch-config libmagickcore-6-headers libmagickcore-6.q16-6-extra libmagickcore-6.q16-dev libmagickwand-6-headers libmagickwand-6.q16-dev libmagickwand-dev libmount-dev libmpdec2 libopenexr-dev libopenexr23 libopenjp2-7-dev libpango-1.0-0 libpangocairo-1.0-0 libpangoft2-1.0-0 libpcre16-3 libpcre3-dev libpcre32-3 libpcrecpp0v5 libpixman-1-0 libpixman-1-dev libpng-dev libpng-tools libpthread-stubs0-dev libpython3-stdlib libpython3.7-minimal libpython3.7-stdlib libreadline7 librsvg2-2 librsvg2-common librsvg2-dev libselinux1-dev libsepol1-dev libsm-dev libsm6 libthai-data libthai0 libtiff-dev libtiffxx5 libtool libwmf-dev libwmf0.2-7 libx11-dev libxau-dev libxcb-render0 libxcb-render0-dev libxcb-shm0 libxcb-shm0-dev libxcb1-dev libxdmcp-dev libxext-dev libxml2-dev libxrender-dev libxrender1 libxt-dev libxt6 mime-support python3 python3-distutils python3-lib2to3 python3-minimal python3.7 python3.7-minimal readline-common shared-mime-info uuid-dev x11-common x11proto-core-dev x11proto-dev x11proto-xext-dev xorg-sgml-doctools xtrans-dev zlib1g-dev && \
    rm -rf /var/lib/apt/lists/*

管理所需的APT软件包列表可能会很混乱，因此我开发了一个脚本来处理这个问题。你可以像这样简单地编写：

FROM php:7.1

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/bin/

RUN install-php-extensions imagick

这个 install-php-extensions 脚本支持在这里列出的PHP扩展。
