browser unable to load latest node version

i’m running my Mocha scripts via Browserify in browser but got the following error in browser’s console:

“Uncaught Error: Sync-request requires node version 0.12 or later. If you need to use it with an older version of node you can npm install sync-request@2.2.0, which was the last version to support older versions of node.”

However installed nodejs’s version on machine is `v9.5.0’

Synchronous requests aren’t really possible in the browser (they’re possible but deprecated). Even in node, I’d recommend only doing requests asynchronously.

You cannot get spawn-sync to work in the browser. That is literally impossible. What you can do is use sync-request in the browser, because it provides a separate implementation specifically tailored for the browser.

That grunt file is too large for me to want to get into unpicking and debugging what’s going wrong. My advice would be to start with the simplest setup you can possibly have to demonstrate the problem. i.e. use grunt-browserify (with no other grunt modules) to build a script that just contains var sr = require('sync-request');sr('GET', '/'); and see if you can get the resulting script to run without error.

If that still errors, you’ll be able to post a really succinct example of what fails, and it’s much more likely that someone will have time to help you figure out what’s going wrong.
