TypeError: util.promisify is not a function

[tgrrr]

I'm having "fun" getting this package to initially load

// App.js
const branch = require('git-branch');
console.log('gitBranch', branch);

TypeError: util.promisify is not a function
(anonymous function)

  3 | const fs = require('fs');
  4 | const util = require('util');
  5 | const find = require('findup-sync');
> 6 | const readFile = util.promisify(fs.readFile);

tested with:
node v8.11.4 and v.9.3.0

Hmm, strange. here are the docs for util.promisify(). Can you provide more information about your environment? Are you using electron? etc...

After it didn't work, I isolated it with a new create-react-app

{
  "name": "create-react-app-demo",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.4.1",
    "react-dom": "^16.4.1",
    "react-scripts": "1.1.4"
  },

I've checked the docs. The error is sometimes based on node < 8. But I'm not using that in this case.

what is the output of node -v on your system?
