Docker-php-ext-install mcrypt缺少文件夹

Question

我尝试在基于php:7.2-apache的docker镜像中安装mcrypt。因此，我使用文档中的RUN-Command并回答here但我收到此错误：

error: /usr/src/php/ext/mcrypt does not exist


usage: /usr/local/bin/docker-php-ext-install [-jN] ext-name [ext-name ...]

   ie: /usr/local/bin/docker-php-ext-install gd mysqli
   /usr/local/bin/docker-php-ext-install pdo pdo_mysql
   /usr/local/bin/docker-php-ext-install -j5 gd mbstring mysqli pdo pdo_mysql shmop

if custom ./configure arguments are necessary, see docker-php-ext-configure

Possible values for ext-name:
bcmath bz2 calendar ctype curl dba dom enchant exif fileinfo filter ftp  gd gettext gmp hash iconv imap interbase intl json ldap mbstring mysqli oci8  odbc opcache pcntl pdo pdo_dblib pdo_firebird pdo_mysql pdo_oci pdo_odbc pdo_pgsql pdo_sqlite pgsql phar posix pspell readline recode reflection session shmop simplexml snmp soap sockets sodium spl standard sysvmsg sysvsem sysvshm tidy tokenizer wddx xml xmlreader xmlrpc xmlwriter xsl zend_test zip

Some of the above modules are already compiled into PHP; please check
the output of "php -i" to see which modules are already loaded.
ERROR: Service 'web' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y          libfreetype6-dev          libjpeg62-turbo-dev          libmcrypt-dev          libpng-dev     && docker-php-ext-install -j$(nproc) iconv mcrypt gd mbstring zip' returned a non-zero code: 1

我的Dockerfile：

FROM php:7.2-apache

RUN apt-get update && apt-get install -y \
     libfreetype6-dev \
     libjpeg62-turbo-dev \
     libmcrypt-dev \
     libpng-dev \
&& docker-php-ext-install -j$(nproc) iconv mcrypt gd mbstring zip
#    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
#    && docker-php-ext-install -j$(nproc) gd


COPY ./etc/000-default.conf /etc/apache2/sites-available/

EXPOSE 80

有谁知道如何解决或如何在请求的文件夹中获取所需的文件？

谢谢！

Answer 1

自7.2以来，mycrypt扩展没有提供PHP源代码，而是通过PECL提供。要在docker中安装PECL扩展，请使用pecl install下载并编译它，然后使用docker-php-ext-enable启用它：

pecl install mcrypt-1.0.2
docker-php-ext-enable mcrypt

Answer 2

要安装mcrypt扩展，您必须确保安装了必需的libmcrypt-dev。

尝试添加：

RUN apt install libmcrypt-dev

在您尝试安装php的扩展之前。

更新

尝试先跑：

docker-php-ext-configure mcrypt

然后

docker-php-ext-install mcrypt

Answer 3

在MoiioM的回答基础上，这对我使用来自PHP的7.2-stretch Docker图像起作用了

RUN apt-get update && apt-get install -y libmcrypt-dev \
    && pecl install mcrypt-1.0.2 \
    && docker-php-ext-enable mcrypt
