How to resolve composer install complaint "Your lock file does not contain a compatible set of packages."

The documentation states:

To install the project, clone it from GitHub and install the PHP dependencies using Composer:

git clone git://github.com/pdsinterop/php-solid-server.git \
    && cd php-solid-server \
    && composer install --no-dev --prefer-dist

But when this is run, errors appear

Thank you for taking the time to report this!

As you can see in the pinned issue #56, PHP 8 is not yet supported. That is what is causing the errors you encounter during composer install.

Although the underlying PHP packages this project uses are still actively being maintained, this project is currently not receiving active development. Our current focus is on the multiuser-php-solid-server and the Solid Nextcloud plugin.

Depending on your desired outcome, I would suggest one of the following:

• Using composer install --ignore-platform-reqs to get the defined versions of the dependencies installed
• Updating the dependency versions in the composer.json file to get newer versions of the dependencies installed
• Using the pdsinterop/multiuser-php-solid-server to get newer versions of the dependencies and support for more than one Solid user on the server (although that does not support your PHP version 8.4.17 either. Only PHP up to 8.3)
