From what I can tell from the setup script, it does not specify a python version for the venv. Mine picks 3.13.7, and the first error I got was while building numpy. Is any particular version of python required? Removing the version did not help. After many hours, the last error was with langchain.
Also, readme should instruct to install with
sh setup_writingway.sh
on linux instead of "source". "Source" will fail on some shells.
