Sharp: Package libffi was not found in the pkg-config search path

It's me again on MacOS. Can't install sharp again. Here the whole output

Any clues?

Hello, it looks like you're using a globally-installed version of vips installed by homebrew.

Has brew update && brew upgrade been run to eliminate any problems/inconsistencies with the dependencies it manages?

[binarykitchen]

Nope, brew update && brew upgrade doesn't make a difference. Still seeing the same error.

Any clues, tips, how to fix this?

[lovell]

If you want to use a homebrew-managed version of vips then brew reinstall vips.

If you'd prefer to use sharp-managed version of vips then brew uninstall vips.

[binarykitchen]

ok that worked, uninstalling vips via brew. confusing. can you add a warning about this to improve DX?

[lovell]

At install-time, sharp logs the decisions it's making - here's the salient part of the log from your initial comment:

info sharp Detected globally-installed libvips v8.7.4
info sharp Building from source via node-gyp

Errors from node-gyp after this in the install log usually relate to an invalid/corrupt installation of libvips and/or its dependencies, which is what you were seeing. By removing the globally-installed libvips you allowed sharp to make a different decision and download and use its own libvips.

Coincidentally I just ran into this same error on an OS X machine:

Package libffi was not found in the pkg-config search path.
Perhaps you should add the directory containing `libffi.pc'
to the PKG_CONFIG_PATH environment variable

and was able to fix it by following the instructions in the error message:

export PKG_CONFIG_PATH="${PKG_CONFIG_PATH}:/usr/local/opt/libffi/lib/pkgconfig"

so this was a brew/libffi/pkgconfig problem unrelated to either sharp or libvips.

[binarykitchen]

Ah good to know. Report this problem to either brew, libffi or pkgconfig somewhere?

[axelpale]

Had this issue today. Resolved it with brew uninstall vips.

Development: Why does sharp need the globally managed vips? Could sharp always download its own libvips? Is it just a matter of download time optimization?

Been running into similar issues since using macOS back in 2015 – probably once per year – whenever I try to install sharp in a fresh project. I've always managed to find help here... Thank you! ❤️

FYI, from what I've seen, all of the backends I can test (Qt5Agg, macosx, TkAgg, WxAgg) currently have the same behavior (with the exception of WebAgg and nbAgg):

• Backend uses Python icon
• Backend does not turn off Python icon when all windows are closed
  
  
  
  • Unclear if this is because backends don't stop running when windows are closed
  
  
• Icon is the Python rocketship

WebAgg does not show an icon at all. nbAgg is specifically for embedding in Jupyter notebook/lab, so showing an icon doesn't make sense.
