Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires PHP extension ext-toto * but it is missing from your system. Install or enable PHP's toto extension.
To enable extensions, verify that they are enabled in your .ini files:
- /app/vendor/php/etc/php.ini
- /app/vendor/php/etc/conf.d/apcu.ini
- /app/vendor/php/etc/conf.d/mongodb.ini
- /app/vendor/php/etc/conf.d/opcache.ini
- /app/vendor/php/etc/conf.d/redis.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-toto` to temporarily ignore these required extensions.
Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.
