Arch Linux User Repository

As @drawm mentioned, you should add python-pywavelets as dependency!

Did anyone successfully install all of the dependencies? I end up with this error message

ImportError: The 'packaging.requirements' package is required; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.

I don't understand this because I have python-requirements and python2-requirements installed. Can anyone help me?

The dependency on python-pywavelets (python2-pywavelets) is missing, so there are many import errors if it has not been installed.

The dependency was introduced in https://github.com/scikit-image/scikit-image/commit/c6e5c7095350e931709acd894a54b32c42375822

Please update the "depends" field in the PKGBUILD accordingly.

If you want the up-to-date package, and only the version for python 3, you can modify the PKGBUILD as below.

}

Since there is a python2-scikit-image package already, is it possible to make this PKGBUILD to build only python-scikit-image ?

Would it be possible to relax the dependency on python2-pillow to simply python2-imaging? Psychopy (https://aur.archlinux.org/packages/psychopy/) is supposedly incompatible with pillow but works with PIL. The scikit documentation suggests it works with both pillow and PIL.

I am sorry, fault seems to be on my side.
Building the package the way it is described in your link works fine.
Thanks for your help.

Cannot reproduce the error, package builds fine on my machine with the same command. You may try building it in a clean chroot as described on https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chroot#Convenience_Way

I get this when running "makepkg -sri":

Breche ab...

wait, what am I even talking about... obviously we do have `dask` among the requirements: https://github.com/scikit-image/scikit-image/blob/master/requirements.txt
