Docker-php-ext-install mcrypt missing folder

问题

I try to install mcrypt in my docker image based on php:7.2-apache. Therefore I use the RUN-Command from the documentation and also answerd here but I receive this error:

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

My 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

Has anybody an idea how to solve or how to get the needed files in the requested folder?

Thanks!

mycrypt extension is not provided with the PHP source since 7.2 , but are instead available through PECL. To install a PECL extension in docker, use pecl install to download and compile it, then use docker-php-ext-enable to enable it:

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

回答2:

To install mcrypt extension you have to make sure you did install libmcrypt-dev which is required.

Try to add:

RUN apt install libmcrypt-dev

before you are trying to install extensions for php.

Update

Try to run first:

docker-php-ext-configure mcrypt

and then

docker-php-ext-install mcrypt

Building on MoiioM's answer, this worked for me using the 7.2-stretch Docker image from PHP

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