How one can use PyPy (preferably pypy3) instead of standard python with poetry?

That is, what should be stored in pyproject.toml? Are other changes necessary as well?

Turns out it is as easy as installing pypy3 (for OS X: brew install pypy3) and typing the following in the project directory:

poetry env use /usr/local/bin/pypy3

given that PyPy lays in /usr/local/bin/pypy3.

Resolving all the dependencies for the new environment might be more tricky, but that's for the different questions.

    I ended up using `poetry env use $(which pypy3)`, which is more robust to changes of environments. (My use-case is building a CI pipeline) – FirefoxMetzger Jul 09 '22 at 15:59
