  Problem 1
    - Root composer.json requires PHP extension ext-mysqli * but it is missing from your system. Install or enable PHP's mysqli extension.
 
To enable extensions, verify that they are enabled in your .ini files:

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-mysqli` 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.
