composer.lock requires PHP 7.2

[whikloj]

I was able to install RipRap inside a current claw-playbook, but composer install fails because the composer.lock file was generated with PHP 7.2.

It tries to use an version of proxy_manager that requires PHP 7.2.0

vagrant@claw:/var/www/html/riprap$ sudo composer install
Deprecation warning: Your package name riprap is invalid, it should have a vendor name, a forward slash, and a package name. The vendor and package name can be words separated by -, . or _. The complete name should match "[a-z0-9]([_.-]?[a-z0-9]+)*/[a-z0-9]([_.-]?[a-z0-9]+)*". Make sure you fix this as Composer 2.0 will error.

  Problem 1
    - Installation request for ocramius/proxy-manager 2.2.2 -> satisfiable by ocramius/proxy-manager[2.2.2].
    - ocramius/proxy-manager 2.2.2 requires php ^7.2.0 -> your PHP version (7.1.27) does not satisfy that requirement.
  Problem 2
    - ocramius/proxy-manager 2.2.2 requires php ^7.2.0 -> your PHP version (7.1.27) does not satisfy that requirement.
    - doctrine/migrations v2.0.0 requires ocramius/proxy-manager ^2.0.2 -> satisfiable by ocramius/proxy-manager[2.2.2].
    - Installation request for doctrine/migrations v2.0.0 -> satisfiable by doctrine/migrations[v2.0.0].

You'd need to create the composer.lock with an older version of PHP.

Also, I could submit a PR with the updated composer.lock from the PHP 7.1.27 install if you want.
