Research direction

Start with requirements-dev.txt and compare the greenlet pin with gevent==23.9.1. Run uv pip install -r requirements-dev.txt before and after updating the greenlet requirement, and consider the reported runtime-version mismatch as part of verification. Done means the development dependencies resolve and install successfully.

Written by the indexing model from the issue text.

Description

Problem

Installing dev dependencies fails because package pins conflict:

  • gevent==23.9.1 requires greenlet>=2.0.0
  • The project pins greenlet==1.1.2

So this command cannot resolve dependencies:

uv pip install -r requirements-dev.txt

Additionally the runtime version is not also right.

Solution

Upgrade greenlet to 2.0.0 or higher.

Update requirements-dev.txt:

greenlet>=2.0.0

or pin exactly:

greenlet==2.0.0

Then reinstall:

uv pip install -r requirements-dev.txt

Root Cause

greenlet==1.1.2 is outdated and incompatible with gevent==23.9.1.
