Feature Request

Currently when running poetry-install.py for a specific version the dependencies of that specific poetry version are resolved at install time and may include recently published versions.

For example, poetry==1.1.11 required cryptography>=2.0
This has been incrementing to pull a newer and newer version of cryptography which ultimately broke a CI docker build I run when the newest version started requiring a rust compiler.

It would be great if we could deterministically install poetry - even if that required the 1-time generation of a poetry-install lock file.

Empieza leyendo poetry-install.py y el contexto de constraints.txt en el issue; después, sigue cómo se resuelven las dependencias para una versión de Poetry solicitada. Define cómo se usaría un archivo de lock o de constraints generado; se considera terminado cuando instalar una versión específica de Poetry produce versiones deterministas de las dependencias sin requerir paquetes incompatibles publicados recientemente.
