problem with php5.6

[cipherbullet]

hi, I am serving up some containers that my php should be 5.6.
but I faced with this error unfortunately:

Step 120/251 : RUN if [ ${INSTALL_AST} = true ]; then     printf "\n" | pecl -q install ast-${AST_VERSION} &&     echo "extension=ast.so" >> /etc/php/${LARADOCK_PHP_VERSION}/mods-available/ast.ini &&     phpenmod -v ${LARADOCK_PHP_VERSION} -s cli ast ;fi

I know but what should I do right now?
I am looking to set up some containers such as apache and MySQL to run my web application.
my friend suggested laradock but I can't build workspace image with php5.6
can you help me?

edit .env set WORKSPACE_INSTALL_AST=false

I believe the proper fix for this should be by checking the PHP version before installation

Unfortunately I had to use PHP 5.6 for the first times in ages, on an old Cake PHP project. Setting WORKSPACE_INSTALL_AST to false allowed me to rebuild the workspace container after changing the php-fpm version to 5.6 🍾
