Getting a libcairo error on MacOS 12.6 on M1 #19

This is still happening after running brew install cairo: 

node:internal/errors:841
  const err = new Error(message);
              ^

@RobKohr

I figured out a workaround. In short, replace the outdated bin pdftocairo of x86_64 arch (not working for M1) with M1's.

  1. Remove the outdated bin rm /Users/robertkohr/projects/bingo-pdfkit/node_modules/pdf-poppler/lib/osx/poppler-0.66/bin/pdftocairo
  2. Point the old path to the new bin ln -s -f /opt/homebrew/bin/pdftocairo /Users/robertkohr/projects/bingo-pdfkit/node_modules/pdf-poppler/lib/osx/poppler-0.66/bin/pdftocairo
  3. It should work now 🎉

If this does not work, please check if the paths are correct. Or maybe you just haven't installed poppler for M1, which means /opt/homebrew/bin/pdftocairo does not exist.

IMO: the long-term solution should be making a PR to dynamically pick the right pdftocairo for different runtime env (arm vs x86), so that we don't need to do the workaround every time we npm install pdf-poppler on M1. However, I'm afraid the author doesn't maintain the package anymore (since there's no update since 4 years ago)?

brew install cairo won't fix the issue, because it installed M1-based lib to /opt/homebrew/lib/libcairo.2.dylib which is not compatible with x86_64-based pdftocairo. Even you point the lib with a soft link, it would show an runtime error (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64').
