Installed global libheif and vips but sharp heif errors (node:14-alpine3.14)

Did you see the documentation relating to installation? Yes

Have you ensured the architecture and platform of Node.js used for npm install is the same as the architecture and platform of Node.js used at runtime? Yes

Are you using the latest version? Is the version currently in use as reported by npm ls sharp the same as the latest version as reported by npm view sharp dist-tags.latest? Yes

If you are using npm v6 or earlier and installing as a root or sudo user, have you tried with the npm install --unsafe-perm flag? N/A

If you are using npm v7, does the user running npm install own the directory it is run in? N/A

If you are using the ignore-scripts feature of npm, have you tried with the npm install --ignore-scripts=false flag? N/A

What is the complete output of running npm install --verbose sharp? Have you checked this output for useful error messages? Yes

What is the output of running npx envinfo --binaries --system? System: OS: Linux 5.10 Alpine Linux CPU: (4) x64 Intel® Core™ i7-4770HQ CPU @ 2.20GHz Memory: 131.32 MB / 1.94 GB Container: Yes Shell: 1.31.1 - /bin/ash Binaries: Node: 14.17.6 - /usr/local/bin/node Yarn: 1.22.5 - /usr/local/bin/yarn npm: 6.14.15 - /usr/local/bin/npm

I’m sorry for submitting an issue, but I’m at my wits end.

Background:

• Develop on Mac
• Global Mac libheif and vips installed using brew
• Local run of my app can process heif files
• Docker version can not

Sample Dockerfile mirrors my actual Dockerfile

FROM node:14-alpine3.14

RUN apk update
RUN apk add libheif libheif-dev vips-dev

COPY . .

RUN npm install --verbose sharp
RUN npm i

CMD [ "node", "./index.js" ]

Index.js is basic:

const sharp = require('sharp');
sharp("./sample1.heic").jpeg().toBuffer();

For some reason sharp is not finding my global vips or will vips will not associate my libheif as a dependency

@lovell I got it! Thank you again for putting me on the right path. I had to keep on 3.14 due to some DevOps constraints, but I was finally successful. For those who come after me:

To get Sharp running with heif support in Docker onnode:14-alpine3.14:

• Sharp package must not be greater than v0.28
• Must add build-base libheif vips-dev vips packages to the image using apk add

@mrjackwills Alpine Linux provides armhf packages e.g. https://pkgs.alpinelinux.org/packages?name=vips-dev&branch=edge&arch=armhf - if you’re still having problems please open a new issue.
