Packaging Keytar with an Electron app

I'm using electron-builder (16.6.2) to package my electron application which includes keytar (3.0.2) as a prod dependency.

package.json file includes:

"scripts": {
    "postinstall": "install-app-deps",
    "compile:dev": "webpack-dev-server --hot --host 0.0.0.0 --config=./webpack.dev.config.js",
    "compile": "webpack --config webpack.build.config.js",
    "dist": "yarn compile && build"
},
"build": {
    "appId": "com.myproject",
    "asar": true,
    "files": [
      "bin",
      "node_modules",
      "main.js"
    ]
}

When I run the .app on the same system it runs fine. When I try running it on a different system (or deleting my node_modules) it fails to find keytar.node. When keytar is built, it includes a fully qualified path to that image for my system. I get the following error in the console:

Uncaught Error: Cannot open /Users/Kevin/Work/myproject/node_modules/keytar/build/Release/keytar.node
Error: dlopen(/Users/Kevin/Work/myproject/node_modules/keytar/build/Release/keytar.node, 
1): image not found

I must be missing a step in the build process.
