Expected Results

Expected package to compile

Actual Results

Steps to Reproduce

docker run -it --rm mhart/alpine-node:8 /bin/ash npm install --build-from-source realm

Version of Realm and Tooling

• Realm JS SDK Version: latest
• Node or React Native: node 8
• Client OS & Version: alpine 3.7
• Which debugger for React Native: ?/None

It sounds like you need to include under alpine to get PATH_MAX.

To be honest, we haven't had Alpine Linux on our radar. We will happy to receive a pull request :-)

@andytompkins Any new developments on this?

Unfortunately we need to add support for musl libc in core and sync - it’s not just a matter of rebuilding realm-js.

Hi everyone! Any new on this topic? I'm trying to run a Docker Container with a NodeJS project using realm-js and I'm getting the error: Fatal error in HandleScope::HandleScope Entering the V8 API without proper locking in place
