Please advise on how to fix this issue?

Hi @paulhuiseismic! I'm Dosu and I’m helping the ragflow team.

You’re hitting two common issues:

1. WSL 403 Forbidden from TUNA mirror:
   This usually means the file isn’t available on the mirror or your access is blocked. The fastest fix is to switch to the official PyPI index. You can do this by replacing all pypi.tuna.tsinghua.edu.cn URLs with pypi.org in your uv.lock file, or by updating your mirror configuration to use the default PyPI. This workaround has resolved similar issues for others [source] [source].

2. Windows CMD datrie build failure:
   This error is because datrie requires Microsoft Visual C++ 14.0 or greater to build native extensions. You can resolve this by installing the Microsoft C++ Build Tools [source].

Bonus:
If you’re using a recent version of ragflow (after 2025-12-16), datrie is no longer a required dependency, so updating to the latest version may avoid this build issue entirely [source].

Let me know if you need the exact commands or run into any other errors!

To reply, just mention @dosu.
