Despite the official CrewAI installation instructions indicating `Python >=3.10 <=3.13`,  
command “pip install crewai” fails at dependency tiktoken, attempts to build tiktoken-0.7.0, which does not build on Python 3.13, pyo3 version not supported.

Perhaps a dependency bump to tiktoken-0.8.0 (released Oct 4th) might help?

Error message indicated:

This is a dependency rabbit hole for new users, who are likely to want the most up to date versions of tools, this may present a barrier to adoption.

For Visual Studio Code (PowerShell terminal), the following commands allowed the build of tiktoken-0.7.0 to succeed:

```auto
$env:PYO3_USE_ABI3_FORWARD_COMPATIBILITY = "1"
pip install crewai

```

It’s too early to say if this is a good idea at all or if it will break anything, but it’s one less hurdle.

Good luck all!

For me it only worked when I downgraded to python 3.12.8

Didn’t work for me. My python version is 3.13 and Visual Studio Code version is 1.95.2

We updated the docs to show the stable python versions to use with CrewAI **Python \>=3.10 and \<3.13**

_TLDR: v 3.13 is unstable and will throw the pyo3 error from tiktoken package, so do not use it._
