Method for enforcing a minimum version of Poetry

Poetry 1.1 is not compatible with 1.0, so we need to enforce Poetry version for our development team one way or another.

There is this Stack Overflow question: https://stackoverflow.com/questions/64003868/how-to-enforce-a-minimum-python-poetry-version which currently is unanswered.

Is there a way of specifying a version of Poetry in pyproject.toml that will fail if the executing version of poetry does not match? What effect does [build-system] requires have?

Would be great to make somehow sure that every team member has recent enough poetry.

In future poetry may add (more) non-backwords compatible features.

Is it possible run bash in https://python-poetry.org/docs/pyproject/#scripts ?

And if there would be some “preinstall” hooks (like in Node’s package.json) then it would be possible to create a simple bash script to do the version checking.

Or maybe just add something like

[tool.poetry.checks]
poetry-version="^1.1"

to pyproject.toml

Adding a “plus 1” to this problem. The Node world seems to have solved this problem by specifying node versions with the engineStrict feature.
