Error: sipbuild.api' has no attribute 'prepare_metadata_for_build_wheel'

[Philippe Fremy]

Hi,

Thanks for helping me. The version of pip is upgraded to the latest 
before running the script, so this is not the source of the error.

Here is the rest of the inner exception. I did not notice it at first 
but it seems to fail because it can not find qmake. Which is coherent. 
But it does not explain why the source package was picked up.



  During handling of the above exception, another exception occurred:
