Error using pyvips with libvips 8.6.2 about pyvips HOT 3 CLOSED

It looks like your _libvips.so was generated for libvips 8.5.x. but you're using libvips 8.6.x, so it's trying to use an entry point that does not exist.

I would uninstall pyvips, install the latest libvips, then reinstall pyvips again with --no-cache-dir, to make sure that everything is regenerated.

pip uninstall pyvips
remove libvips
install latest libvips
pip install --user --no-cache-dir pyvips

Perhaps we should add another version check. The _libvips.so extension could record the version of libvips it was generated for (ie. the header version) and compare that to the version of libvips it links against at runtime.

That worked for me. I had uninstalled and reinstalled pyvips, but without --no-cache-dir. Thanks for your help.

git master pyvips now checks that the binary wrapper version matches the shared library version, and falls back to ABI mode if they don't. Hopefully that'll make this kind of error impossible.
