Error : `PHP Fatal error: Uncaught Error: Class "mbolli\nfsen_ng\common\Debug" not found in /var/www/html/nfsen-ng/backend/cli.php:9` when trying to run `cli.php`

[FontouraAbreu]

When trying to run /var/www/html/nfsen-ng/backend/cli.php start I get:

PHP Warning:  include_once(/var/www/html/nfsen-ng/backend/../vendor/autoload.php): Failed to open stream: No such file or directory in /var/www/html/nfsen-ng/backend/cli.php on line 3
PHP Warning:  include_once(): Failed opening '/var/www/html/nfsen-ng/backend/../vendor/autoload.php' for inclusion (include_path='.:/usr/share/php') in /var/www/html/nfsen-ng/backend/cli.php on line 3

This comes from the branch prep-php-82

My current php version is:

root@nfsen-ng:/var/www/html/nfsen-ng/backend# php -v

When I tried to run composer install --no-dev as indicated on https://github.com/mbolli/nfsen-ng/tree/prep-php-82?tab=readme-ov-file#installation I got:

Do not run Composer as root/super user! See https://getcomposer.org/root for details

Your lock file does not contain a compatible set of packages. Please run composer update.

  Problem 1
    - Root composer.json requires PHP extension ext-mbstring * but it is missing from your system. Install or enable PHP's mbstring extension.

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/8.2/cli/php.ini
    - /etc/php/8.2/cli/conf.d/10-opcache.ini
    - /etc/php/8.2/cli/conf.d/10-pdo.ini
    - /etc/php/8.2/cli/conf.d/15-xml.ini
    - /etc/php/8.2/cli/conf.d/20-calendar.ini
    - /etc/php/8.2/cli/conf.d/20-ctype.ini
    - /etc/php/8.2/cli/conf.d/20-dom.ini
    - /etc/php/8.2/cli/conf.d/20-exif.ini
    - /etc/php/8.2/cli/conf.d/20-ffi.ini
    - /etc/php/8.2/cli/conf.d/20-fileinfo.ini

    - /etc/php/8.2/cli/conf.d/20-xsl.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-mbstring` to temporarily ignore these required extensions.

I don't know if the problem with mbstring might be the cause but running composer update takes too much time and returns a timeout error:

The following exception is caused by a process timeout
Check https://getcomposer.org/doc/06-config.md#process-timeout for details

In Process.php line 1204:

  The process "git clone --mirror -- 'https://github.com/phpstan/phpstan.git' '/  
  root/.cache/composer/vcs/https---github.com-phpstan-phpstan.git/'" exceeded th  
  e timeout of 300 seconds.

After running composer install --no-dev --ignore-platform-req=ext-mbstring I was able to run ./cli.php start without errors

root@nfsen-ng:/var/www/html/nfsen-ng/backend# ./cli.php start
2024-02-21 17:30:29 CLI: Starting daemon...
int(0)
Daemon running, pid=1525

This issue can be closed, I hope it helps anyone facing the same problem.

@FontouraAbreu to install mbstring just make an apt install php-mbstring and then phpenmod mbstring.
