Check if you're running the exact Node version you specified in package.json.
npm install node-check --save
// uses defaults (engine=node, manifestFile=package.json);// specifies engine"rhino";// specifies engine and package.json"node" "some/package.json";// specifies engine, package.json and running version."node" "some/package.json" node: "6.8.1";
In practice, you add something like
require("node-check")() to your main Node.js file. If version requirement is not satisfied then an exception will be thrown.
