Failed to build pycairo
ERROR: Could not build wheels for pycairo which use PEP 517 and cannot be installed directly

Should pin the version pip install reportlab==3.5.67

New version can't be use.

Thank you for raising your first issue! Your help to improve svglib is much appreciated!

I guess this is an issue related to reportlab 4. The failed installation is related to your system, it might succeed on other systems with cairo installed, so I don't see us limiting ourselves to reportlab<4. I guess the best solution is that you pin reportlab in your dependencies.
