Unable to pip install without Rust toolchain on Windows 11 (x64)

[dslinger-a2]

I'm getting this error message when trying to pip install on Windows 11 (x64). I don't have this issue if I try to replicate in an Ubuntu docker container or on a different pop!_os laptop. It seemed in the readme that the intention is for the wheels to work for Windows. I'm getting the same error when trying to install a number of different older versions of flatterer on this Windows machine. I understand that I can install the Rust toolchain to resolve this but wanted to bring up the issue.

And this was with Python v3.10.7

@dslinger-a2 thanks for making me aware of this.

It looks like only python 3.9 builds were being made for windows from flatterer version 0.17 and later.

I am trying to make a new release now with python 3.8 - 3.11 for windows.

@dslinger-a2 This has run now, and the latest version should support more python versions for windows. Could you check that it works for you?

Looks good! Thanks so much @kindly!
