Issue

When running poetry install -n -vvv with the pyproject.toml provided above, I get an assertion error. The error gets fixed by changing pytest-inmanta-extensions = {version = "*", optional=true} to pytest-inmanta-extensions = {version = ">=4.5", optional=true}.

[dimbleby]

almost surely a consequence of bogus requirements in pytest-inmanta-extensions.

$ curl -s https://pypi.org/pypi/pytest-inmanta-extensions/json | jq '.info.requires_dist'
[
  "asyncpg",
  "click",
  "inmanta-core (~=9.3.0.dev)",
  "pip2pi",
  "pyformance",
  "pytest-asyncio",
  "pytest-env",
  "pytest-postgresql (>=4)",
  "psycopg (>=3)",
  "tornado"
]

as far as I can see 9.3.0.dev is not a valid version per PEP440 - probably 9.3.0.dev0 was intended.

of course it would be better if poetry rejected and reported the bogus requirement, rather than later being confused by it - but then the install would still have failed.

For long term happniess you likely should submit a merge request to pytest-inmanta-extensions fixing their dependency.
