问题
When attempting to run sharp inside an AWS Lambda function, I keep getting the following error:
darwin-x64' binaries cannot be used on the 'linux-x64' platform. Please remove the 'node_modules/sharp/vendor' directory and run 'npm install'
I deploy my serverless applications with Serverless Framework from my MacBook Pro. How do I fix this problem?

Kudos to stdunbar for steering me in the right direction.
When installing sharp on MacOS via NPM the normal way (i.e.: npm i sharp --save), the installer automatically adds binaries for OS X. But AWS lambda functions run on Linux 2 machines with x64 processors and this is why we get this error.
To fix you must first uninstall sharp completely and then run:
npm install --arch=x64 --platform=linux sharp
Note:
version 0.25 no longer works with the target flag. This used to work:
npm install --arch=x64 --platform=linux --target=10.15.0 sharp
Then deploy as usual from Serverless Framework with sls deploy
Side Note:
Sharp is EXTREMELY FAST!!! Before using sharp, I was using another image resizing utility named Jimp. It did the job, but was quite slow. To prevent timeout errors, I had to increase the memory size from 128 to 512 and the timeout from 5 seconds to 30 seconds just to handle a typical 1 megabyte image.
Here is a comparison between the two for resizing a 1.2Mb picture down to 600x400 using the same configuration:
Jimp -> used 512Mb of memory and AWS billed me for 14300 ms.
Sharp -> used 132 MB of memory and AWS billed me for 800 ms.
That's more than 14x faster than Jimp!!!

I was facing the same issue, when i do npm install --arch=x64 --platform=linux sharp in CMD in windows machine.
Fixed it by opening the CMD in Administrator mode, i did not find any error in running npm install --arch=x64 --platform=linux sharp
