Looking at vips specfile, it looks like a mistake that vips-tools-8.7.4-2.fc30 requires /usr/bin/python2. If it is on purpose, please explain why it is needed. Thanks.
Looks like it's for vipsprofile, which hasn't been ported to Python 3. There's some context at https://github.com/libvips/libvips/issues/667.
Thanks. Let's fix that? https://github.com/libvips/libvips/pull/1262
Anyway, there is a missing dependency now:
Traceback (most recent call last):
File "/usr/bin/vipsprofile", line 5, in <module>
ImportError: No module named cairo
My upstream pull request was merged.
This will be fixed in 8.8.2-2, which is heading to Fedora 31. Thanks for the report and for working on this!
