1) Confirming that the environment is in sync with my definition file (pyproject.toml or lockfile) is my true objective. If I suddenly add libraryFoo to pyproject.toml, but I forget to run `poetry install`, I want my `make test` command to note the discrepancy and correct the situation. 2) I think that has some brittleness of detecting where the environment lives (as per the author's post). For my use case, I would be fine assuming the defaults, but it is something else to go wrong Edit: Thinking out loud, I guess the quickest solution is to checksum the pyproject.toml file and store that somewhere. If current hash matches previous, do not run `poetry install`. While that would get me there, I am hoping for a first-party, standard solution.
