Issue

Hi, I was trying out the beta release and thought you might find this bug interesting.

When switching from 1.0.10 to 1.1.0b1 poetry misses two sub-dependencies. To reproduce: run poetry install with 1.0.10 and note that jsonschema is in the poetry.lock file. When using 1.1.0b1 jsonschema is no longer in the lockfile.

This was resolved with python-poetry/poetry-core#55 will be fixed in mainline poetry with the next poetry-core release. In the meanwhile if you wish to use the fix you can do so by updating poetry-core manually.

If you have installed poetry using pipx you can do something like this. Obviously this assumes this is a fresh install of poetry.

pipx install --pip-args='--pre' poetry
pipx inject --pip-args='--force' poetry 'poetry-core @ git+https://github.com/python-poetry/poetry-core.git'
