Error trying to build Cantera with option `python_sdist="yes"`

I encountered an error (shown below) when I use the option python_sdist="yes"

Does anyone know what causes this issue?

[42n8dzydoo]

Apparently, there is a directory missing at cantera/interfaces/cython/cantera/data.

I created an empty data directory in the path. I do not know if this is actually meant to be empty. But this resolved the error in my compilation.

Please, can someone help with this?

Thanks in advance!

Hi, thanks for raising this! I think this is a conflict or a poor dependency resolution between the interfaces, probably a bug in the configuration. In any case, the python_sdist is not necessary for general operation or install of the Python interface, it's really only useful to upload to PyPI. I'd suggest turning that option off unless you have a specific use for it.
