Florencia,
Muchas gracias, ahí instale la versión 1.10.17, y al ejecutar composer install me sale el siguiente error:
our requirements could not be resolved to an installable set of packages.
Problem 1
- The requested PHP extension ext-apcu * is missing from your system. Install or enable PHP's apcu extension.
Ejecute el siguiente comando apt-get install php-apcu y me devuelve que ya lo tengo instalado Reading package lists... Done
Building dependency tree
Reading state information... Done
php-apcu is already the newest version (5.1.19+4.0.11-7+ubuntu20.04.1+deb.sury.org+1).
0 upgraded, 0 newly installed, 0 to remove and 14 not upgraded.
que me estaría faltando?
