Building from source, like:
meson setup build --prefix /my/install/prefix
cd build
meson compile
meson test
meson install

Every thing is Ok, before "meson install":

ERROR: Unhandled python OSError. This is probably not a Meson bug, but an issue with your build environment.

So, Any idea?

Hello @dythbj,

meson setup build --prefix /my/install/prefix

You need to pick an install prefix. I often use /Users/john/vips, for example.

It's probably simpler to use homebrew though. Just brew install vips and it should do everything for you.

Ok, brew install vips, Thanks alot!
