Poetry - resolving latest langchain, langchain-openai and crewai - results in conflict

[jedi4ever]

I'm trying to use the latest version of langchain, langchain-openai and crewai together in a project. For some reason the resolution of poetry woes.

To reproduce:

• blank new project poetry init
• poetry add langchain
• poetry add langchain-openai
• poetry add crewai

(langchain-openai-crewai-poetry-py3.12) patrickdebois@esp32-462BF0 langchain-openai-crewai-poetry % poetry add langchain
Using version ^0.1.7 for langchain

Because no versions of crewai match >0.11.2,<0.12.0
 and crewai (0.11.2) depends on langchain-openai (>=0.0.5,<0.0.6), crewai (>=0.11.2,<0.12.0) requires langchain-openai (>=0.0.5,<0.0.6).
So, because langchain-openai-crewai-poetry depends on both langchain-openai (^0.0.6) and crewai (^0.11.2), version solving failed.
