Unable to install CrewAI - Get a VSwhere error

Question

While installing CrewAI using Pip install CrewAI , I was asked to install Vswhere.exe, which I did by installing MSBuild Tools with C++ however I still get this error while installing numpy. Wonder what else i am missing?

Build type: native build Project name: NumPy Project version: 1.26.4 WARNING: Failed to activate VS environment: Could not parse vswhere.exe output

Was expecting a clean install of numpy library to start build some agents. I am doing this install on a Windows11 laptop.

FUll Error output below

Answer 1

Resolved this error by installing Visual Studio build however main problem seems to be packaging issues not supported by Python 3.12 and 3.13. Original pip install for crew worked with python 3.11.
