Description

I'm not entirely sure if this counts as a bug as I'm not entirely sure if the use of this package is supported on AWS Lambda, but I wanted to post this somewhere so as to have a record in case anyone else tries to use it on Lambda.

In any case, I was using this locally to develop a lambda function and when I pushed it to the AWS Lambda environment I ran into the following error: "/var/task/node_modules/spellchecker/build/Release/spellchecker.node: invalid ELF header". I looked into it and discovered the issue was my node modules weren't being built in the correct environment as used by lambda.

After a bunch of investigation and testing I was eventually able to find a docker image that was able to build the modules in an environment as similar to that used by lambda. However, when I ran the lambda I got this error: "SyntaxError: Unexpected token '.'",

I wasn't entirely sure what was going on until I looked at the logs of the docker build. I noticed the following:

I'm not familiar with the linux build environment so I couldn't exactly decipher what all that means. However, I'm get the impression how spellchecker was built in that linux environment is somehow incompatible with the node runtime or there's some issue with how it was built. But I don't really know. I see a lot of warnings in there but no errors.

I did find this issue in electron-spellchecker which is related.
