I have python 3.10 installed with conda (conda create --name py310 python=3.10; conda activate py310) After installing nile and running nile init, I get

I installed greenlet==1.1.2 and still have the same error. I also can’t find any frozendict directory, neither in lib nor lib64.

Python 3.10 is not supported, the cairo language doesn’t support it either. It’s recommended to change python versions.
