Poetry doesn't raise error if using wrong python version

[anth2o]

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: macOS 12.2.1

• Poetry version: 1.1.13

• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/anth2o/17c459b8d1e188b8f31791aca79e9b58

Issue

I have an issue when using Poetry. If I use a pyproject.toml similar to the one of the Gist, I want to constrain Python versio to be 3.10.*.
But if I'm trying to install this package using a lower version (for instance 3.9), I don't have any error displayed:

$ python -V
Python 3.9.12
$ poetry env info

Python:         3.9.12

Writing lock file

I think this is a serious issue since might want to force some Python version and this conflict is silently ignored. The issue is the same if I specify a lower version in the pyproject.toml.

Hello @anth2o,

this is already improved in the latest preview version (1.2.0b1) by #4520.
