delocate.delocating.DelocationError: wheel/PIL/.dylibs/libwebp.7.dylib already exists

This has started happening for Python 3.8 on macOS since Travis changed from a 10.13.3 image to a 10.13.6 image:

Would you mind adding a line delocate-listdeps Pillow-6.2.1-cp38-cp38-macosx_10_9_x86_64.whl in your config, to see where the libraries come from?

[hugovk]

Sure, where would be a good place?

Somewhere in:

https://github.com/python-pillow/pillow-wheels/blob/master/config.sh

Or in?

https://github.com/python-pillow/pillow-wheels/blob/master/.travis.yml

[matthew-brett]

Aha - yes - it's not very straightforward. I think you can add this to config.sh:

function repair_wheelhouse {
    local wheelhouse=$1
    install_delocate
    delocate-listdeps $wheelhouse/*.whl
    delocate-wheel $wheelhouse/*.whl # copies library dependencies into wheel
}

Thanks, with that, I get:

This has been fixed by @radarhere in python-pillow/pillow-wheels#134 by switching the osx_image.

Thanks both!
