I looked for the folder /usr/local/opt/python/bin/python but i don't have it.

If i do which Python in the Terminal i get /usr/bin/Python which i guess should be where the script should look for Python.

Can i somehow alias the correct folder to allow libvips to build?

I fixed the error by installing python via homebrew aswell.

So i did homebrew install python first and then brew install homebrew/science/vips --with-webp --with-graphicsmagick afterwards.
