POLYMER 4.16.1 make error

Dear sakvaka_env,

Thank you for your so details explain.
Is that mean i should use the old version with Cpython, maybe Cpython 2.0 will be work.

That's one option, but another is to modify setup.py like this to force Cython to use Python 2:

Code: Select all

It would be nice to have a POLYMER v4.16.2 release that adds the 'language_level' to the setup.py or even better updates the Python-2 files of POLYMER to Python-3 (Python 2 reached end of life in 2019). Using cython<3 is just a workaround which will increasingly block other requirements from updating in future.

Thanks for this. A major update of Polymer is underway, we will pay attention to this topic for next release.
Kind regards,
François
