Seems its happening because of latest version of litellm(needs uvloop-0.21.0. which does not support windows) I manually installed litellm==1.57.4 and was able to install crewai. ---

I’m running LiteLLM version 1.57.4 but I’m still getting the uvloop error message when i attempt “crewai install”. Any thoughts on how to fix this? Thanks.

Have you activated venv? another way you can try is adding dependency in .toml file dependencies = [ “litellm==1.57.4” ] ---
