Docker php 7.1 imagick:-

pecl install imagick \
&& docker-php-ext-enable imagick \

• No releases available for package "pecl.php.net/imagick" install failed

错误:服务'app'构建失败

ERROR: Service 'app' failed to build

推荐答案

来自官方 docker图片文档:

"E:软件包'php-XXX'没有安装候选对象""

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

从docker-library/php#542开始，此图像阻止Debian的PHP软件包的安装.docker-library/php#551(注释)中对此更改进行了其他讨论，但要点是，在此映像中安装Debian的PHP软件包会在单个映像中导致两次冲突的PHP安装，这几乎肯定不是预期的结果.

As of docker-library/php#542, this image blocks the installation of Debian's PHP packages. There is some additional discussion of this change in docker-library/php#551 (comment), but the gist is that installing Debian's PHP packages in this image leads to two conflicting installations of PHP in a single image, which is almost certainly not the intended outcome.

对于那些被此更改破坏并在开发适当的修补程序的同时寻求解决方法的人，在Dockerfile中添加以下简单行应删除该块(强烈警告:这将允许安装第二次安装PHP，除非您真的知道自己在做什么，否则绝对不是您要找的东西:

For those broken by this change and looking for a workaround to apply in the meantime while a proper fix is developed, adding the following simple line to your Dockerfile should remove the block (with the strong caveat that this will allow the installation of a second installation of PHP, which is definitely not what you're looking for unless you really know what you're doing):

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

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

此错误的正确解决方案是要么使用FROM debian:XXX并直接安装Debian的PHP软件包，要么使用docker-php-ext-install，pecl和/或phpize安装必要的其他扩展和实用程序.

The proper solution to this error is to either use FROM debian:XXX and install Debian's PHP packages directly, or to use docker-php-ext-install, pecl, and/or phpize to install the necessary additional extensions and utilities.

解决方案

Dockerfile:

The Solution

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/*

使用以下方法构建它:

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