jest-haste-map: watch error complaining that it can't find a file in the jest-haste-map node_modules folder

I just upgraded to RN 0.56.0 and am using jest version: 22.4.3 (updating the jest version doesn't help) When I try to run my test suite, I get the following error in the terminal:

jest-haste-map: watch error: Error: ENOENT: no such file or directory, 
open '/Users/mobilepractice/builds/0bcf5ed0/0/cx-mobile/posting- 
plus/PostingPlus/node_modules/jest-haste-map/build/worker.js' at Error

Object.require.extensions.(anonymous function) [as .js]

Function.Module._load (module.js:438:3) at Module.require 
(module.js:497:17) at require (internal/module.js:20:19)

and this error as well:

/Users/mobilepractice/builds/0bcf5ed0/0/cx-mobile/posting- 
plus/PostingPlus/node_modules/react-native/jest/hasteImpl.js:50 ) /*: 
string | void */ { ^ SyntaxError: Unexpected token ) at

plus/PostingPlus/node_modules/jest-runtime/node_modules/jest-haste- 
map/build/worker.js:16:19) at next (native)

I can see the worker.js file in my node_modules folder, which is why the ENOENT error is confusing.

A solution is to make sure node 8 or higher is installed. This error occurs on node 6.9.1.
