Bug

Description

Documentation sates that node v4.1 and v5.7 are tested for use with sunder. However, underlying dependency electron-rebuild (v.1.5.7) requires node>=6 (see https://github.com/electron/electron-rebuild/blob/v1.5.7/package.json#L28)

Steps to Reproduce

npm install on master branch with node 4.x or 5.x and observe the following error:

/Users/m/src/sunder/node_modules/electron-rebuild/lib/src/rebuild.js:73
                depKeys.push(...Object.keys(rootPackageJson.dependencies || {}));
                             ^^^
