Cannot find module 'sharp' error on AWS lambda

Hi,

Currently I am mounting express server to AWS lambda.

But lambda keep throwing error "Cannot find module 'sharp'"

sharp worked very well at express server but not here lambda

I tried sharp version 0.20.1 nodejs 8.10

I tried these on

http://sharp.pixelplumbing.com/en/latest/install/

rm -rf node_modules/sharp docker run -v "$PWD":/var/task lambci/lambda:build-nodejs8.10 npm install but not working

It would be really appreciated to help me to solve this error

@wingtree - here are some things to check:

You mentioned you are using serverless-webpack so using serverless framework to deploy? If so the best option is to explicitly tell serverless-webpack plugin what modules you want to include in your bundle (this keeps your zip to the smallest size possible, for faster uploading). Here’s my config for example: https://github.com/mbudm/fotopia-serverless/blob/master/serverless.yml#L515-L521

Another thing that just threw me was that with the move to 10.x in LTS my CI build was now packaging sharp and my other modules in a different node version to the lambda environment. This produced an error like https://github.com/lovell/sharp/issues/1197. Changing my travis-ci build config to explicitly use node v8.10.0 fixed this.

May not be your issues but definitely things to watch out for.

@lovell Of course I included sharp in externals of webpack.config.js This sharp worked very well at original express server (and I used webpack too here)
