Custom libvips loads and saves HEIC, pdf, etc. but Sharp not

[Michiel Swaanen]

Possible bug

Is this a possible bug in a feature of sharp, unrelated to installation?

• Running npm install sharp completes without error.
• Running node -e "require('sharp')" completes without error.

If you cannot confirm both of these, please open an installation issue instead.

Are you using the latest version of sharp?

• I am using the latest version of sharp as reported by npm view sharp dist-tags.latest.

If you cannot confirm this, please upgrade to the latest version and try again before opening an issue.

If you are using another package which depends on a version of sharp that is not the latest, please open an issue against that package instead.

What is the output of running npx envinfo --binaries --system --npmPackages=sharp --npmGlobalPackages=sharp?

Does this problem relate to file caching?

The default behaviour of libvips is to cache input files, which can lead to EBUSY or EPERM errors on Windows.
Use sharp.cache(false) to switch this feature off.

Didn't test this because I'm not running on Windows

• Adding sharp.cache(false) does not fix this problem.

What are the steps to reproduce?

Run bash scripts/start.sh to get started, Docker is a prerequisite.

What is the expected behaviour?

Sharp should convert the custom file types added to the custom libvips build. While libvips can handle these conversions, Sharp currently does not.

Adding the following line to the Dockerfile + pnpm add node-addon-api node-gyp did the trick.

ENV SHARP_FORCE_GLOBAL_LIBVIPS=1

Thanks for the help, somehow looked over this in the docs 👀
