Estoy tratando de ejecutar la instalación del compositor para un proyecto laravel. El error es el siguiente:

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update to update them.
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for namshi/jose 5.0.2 -> satisfiable by namshi/jose[5.0.2].
    - namshi/jose 5.0.2 requires lib-openssl * -> the requested linked library openssl has the wrong version installed or is missing from your system, make sure to have the extension providing it.
  Problem 2
    - namshi/jose 5.0.2 requires lib-openssl * -> the requested linked library openssl has the wrong version installed or is missing from your system, make sure to have the extension providing it.
    - tymon/jwt-auth 0.5.9 requires namshi/jose 5.0.* -> satisfiable by namshi/jose[5.0.2].
    - Installation request for tymon/jwt-auth 0.5.9 -> satisfiable by tymon/jwt-auth[0.5.9].

Investigué eso, parece que PHP en mi Mac no tiene openSSL. Pero cuando corro

php -m

Hay un módulo openssl en la lista.

Por lo tanto, no entiendo cuál es el problema.

Aquí está mi compositor.json

}

PD: Acabo de recibir un nuevo Mac Pro, no tengo tiempo para instalar MAMP y Xcode, así que supongo que el php que utilicé está construido internamente
