Error 1:

$ npm start

  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Error: The module '/home/k18p/gzweb/gzbridge/build/Debug/gzbridge.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION -1268563576. This version of Node.js requires
NODE_MODULE_VERSION 67. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

The NODE_MODULE_VERSION values increment across runs every time till overflow eventually becoming negative.
