Otherwise, either add it to your pyproject.toml under: [tool.uv.extra-build-dependencies] youtokentome = ["Cython"] or uv pip install Cython into the environment and re-run with --no-build-isolation. help: youtokentome (v1.0.6) was included because app (v0.1.0) depends on rudalle (v1.1.3) which depends on youtokentome
