## Known Issues
### macOS AMD64 Python 3.13 Compilation Failures
**Issue**: Nightly/release builds may fail on macOS AMD64 with Python 3.13 due to `chroma-hnswlib` compilation errors:
```
clang: error: unsupported argument 'native' to option '-march='
error: command '/usr/bin/clang++' failed with exit code 1
```
**Root Cause**: Systematic difference in dependency resolution between workspace builds vs published packages:
| Build Type | Package Source | Dependencies | chromadb | Result |
|------------|----------------|--------------|----------|---------|
| **Manual/Source** | Workspace (`langflow-base = { workspace = true }`) | 162 packages | ❌ Not included | ✅ Success |
| **Nightly/Release** | Published (`langflow-base-nightly==0.5.0.dev21`) | 420 packages | ✅ Included | ❌ Compilation fails |
**Technical Details**:
1. **Workspace builds** use local `src/backend/base/pyproject.toml` which excludes `chromadb`
2. **Nightly builds** modify dependencies via `scripts/ci/update_uv_dependency.py`:
- Changes: `langflow-base~=0.5.0` → `langflow-base-nightly==0.5.0.dev21`
- Uses published PyPI package with full dependency tree including `chromadb==0.5.23`
3. **macOS clang** doesn't support `-march=native` flag used by `chroma-hnswlib` compilation
**Workarounds**:
- Manual testing (source builds) works consistently
- Issue only affects nightly/release automated builds
- Some runs may succeed if compatible `chroma-hnswlib` wheels are available on PyPI
**Files Involved**:
- `scripts/ci/update_uv_dependency.py` - Modifies dependency resolution
- `scripts/ci/update_pyproject_combined.py` - Orchestrates nightly build changes
- `pyproject.toml` vs `src/backend/base/pyproject.toml` - Different dependency trees
## Results
- ✅ **Success**: All platforms pass installation and basic functionality
