  ERROR: Failed building wheel for lxml
Failed to build lxml
ERROR: Could not build wheels for lxml, which is required to install pyproject.toml-based projects

I updated my macOS system to the latest. Ensured Xcode is installed. Tried to uninstall and reinstall lxml. But the same error persists. Anyone encountered the same?
