zip-it-and-ship-it: Problem with running Netlify function: Cannot find module '../build/Release/sharp.node'

- Do you want to request a feature or report a bug? bug

- What is the current behavior? I’m including the sharp module in my deploy-building.js Netlify function. I’m resizing some images and uploading them to an S3 bucket.

When invoking the function in the Netlify dev environment, it works. However, when I deploy my feature branch in a deploy preview, it does not work. These are the logs from building the site (that are relevant to sharp):

Here are the function’s logs when it tries to run:

3:15:26 PM: 2020-01-15T21:15:26.407Z	undefined	ERROR	
Something went wrong installing the "sharp" module

Cannot find module '../build/Release/sharp.node'

- Remove the "node_modules/sharp" directory, run "npm install" and look for errors
- Consult the installation documentation at https://sharp.pixelplumbing.com/en/stable/install/
- Search for this error at https://github.com/lovell/sharp/issues

- If the current behavior is a bug, please provide the steps to reproduce.

1. Have a JS Netlify function deploy-building.js that requires sharp: const sharp = require('sharp');
2. Push to Github PR, which notifies Netlify to publish a deploy preview. (We have Netlify configured to deploy PRs automatically.)
3. Site builds, but because deploy-building.js did not exist yet, it will not have run during the very first build.
4. Retry deploy in Netlify’s UI.
5. deploy-building.js runs and logs that something went wrong with sharp.

- What is the expected behavior?

I expect my function to be able to find and use the sharp module.

- Please mention your node.js, and operating system version.

Locally, I’m using node v11.9.0. I’m on a MacBook Pro running macOS Mojave v10.14.5.

I understand that sharp is a native module, and that it installs a different version for me locally than it installs on Netlify, so I don’t think it’s a differing environments issue.

I also set the AWS_LAMBDA_JS_RUNTIME environment variable on Netlify to nodejs10.x, mostly because I was running out of ideas and I thought maybe it would help because of what I had been reading in sharp’s installation docs: https://sharp.pixelplumbing.com/en/stable/install/#aws-lambda

At any rate, it was giving me the same errors before I set that variable.
