Hello,

I want to use napa, but when run my following simple code:

const napa = require('napajs');
    const zone1 = napa.zone.create('zone1', { workers: 2 });

    // Broadcast code to all 4 workers in 'zone1'.
    zone1.broadcast('console.log("hello world");');

it throw error:

Error: dlopen(xxx/node_modules/napajs/bin/napa-binding.node, 1): no suitable image found.  Did find:
