poetry add pymilvus fails dependency resolution on versions before 2.4.4

The problem

Issue milvus-io/pymilvus#2131 (closed, 10 comments): Creating a fresh environment with poetry and running poetry add pymilvus=^2.4.3 fails during dependency resolution. The reporter expected a clean install and instead got a resolver error that never appeared with pip, which pointed at how pymilvus declares its platform-specific dependencies.

What to do

Poetry's resolver choked on pymilvus's platform-conditional dependencies. Maintainer XuanYang-cn shipped the fix in pymilvus 2.4.4 (via PR #2136, which added proper Windows platform checks so the environment markers resolve cleanly under poetry). Resolution: upgrade to pymilvus 2.4.4 or newer and rerun poetry add.
