Finding or installing Composer on the server 

If composer is not found when you run it, you may need to use a full path or install it manually.

Try finding the PHP and Composer paths using which:

$ which php
/opt/php-8.3/bin/php
$ which composer
/usr/local/bin/composer

Use full paths instead of just composer, for example:

/opt/php-8.3/bin/php /usr/local/bin/composer create-project \
    "typo3/cms-base-distribution:^13.4" my-new-project

If Composer is not installed, you can download it here: https://getcomposer.org/download/

Then run it like this:

/opt/php-8.3/bin/php composer.phar create-project \
    "typo3/cms-base-distribution:^13.4" my-new-project

Refer to your hosting provider’s documentation if you have multiple PHP versions or need special access.

Example: Use specific PHP versions in the console (jweiland.net)
