Issue

Sorry, a bit sparse on details here, but wanted to report a bug (that is probably rare, so no hard feelings if you close this without action, especially since I have a workaround).

I've been installing poetry via pip

pip install poetry==1.2.0a2

And today I found my application was hard down because poetry was simply no-op'ing (with no output, even with a -vvv) at the

poetry install --default --sync

step of my deploy pipeline.

I eventually discovered this was due to poetry-core drifting to 1.1.0b2 without me knowing.

I pinned poetry-core back to 1.1.0a7 and everything went back to normal as expected.

This is not unexpected -- our current situation with unpinned poetry-core versions is less than ideal, but the reality of our prereleases is only the latest version is supported. Because an improved pre-release poetry-core has been released to support a new Poetry pre-release, this incompatibility has occurred. The solution is to update to Poetry 1.2.0b2 and validate it works in your environment ahead of a full release.
