How to update your composer package stored in git?

Question

git

I have a project. The project is stored in gitLab and works on different sites.
Also, a library from a closed repository is connected to the project through composer.
composer.json

"require-dev": {
        "project/name": "*",
    },
    "repositories": [
        {
            "type": "vcs",
            "url": "[email protected]###.ru:project/name.git"
        }
    ],

The problem is the following, I update this library via composer update on one of the sites and successfully push the changes to the server, on the other site I do git pull && composer update and the library code does not update. composer says there are no changes.
What to do?
