Cannot install via composer

The current setup does not allow us to install via composer like I hoped it would 🙈
docker run --publish=80:80 --name=t4 -tid tripalproject/tripaldocker:latest
docker exec -it t4 service postgresql restart
docker exec -it t4 bash
root@cc02cf03ce2e:/var/www/drupal/web# composer require tripalcultivate/trpcultivatetheme

Installation failed, deleting ./composer.json.

  No composer.json present in the current directory (./composer.json), this may be the cause of the following exception.

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires tripalcultivate/trpcultivatetheme * -> satisfiable by tripalcultivate/trpcultivatetheme[4.x-dev].
    - tripalcultivate/trpcultivatetheme 4.x-dev requires tripalcultivate/trpcultivatetheme-theme * -> could not be found in any version, there may be a typo in the package name.

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
 - It's a private package and you forgot to add a custom repository to find it

Read <https://getcomposer.org/doc/articles/troubleshooting.md> for further common problems.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require tripalcultivate/trpcultivatetheme:*" to figure out if any version is installable, or "composer require tripalcultivate/trpcultivatetheme:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.
