undefined is not an object (evaluating 'process.version.split') in react-native

Question

After upgrading the RN to 0.62.2 then it failed and then shows the above evaluating 'process.version.split'.

TypeError: undefined is not an object (evaluating 'process.version.split')

The issue is with the rn-nodeify

{
  "scripts": {
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "start": "react-native start",
    "test": "jest",
    "lint": "eslint .",
    "test:debug": "node --inspect node_modules/.bin/jest --runInBand",
    "postinstall": "sh fix-amplify-jank.sh && ./node_modules/.bin/rn-nodeify --install --hack --yarn"
  },
  "dependencies": {
    "url": "^0.10.3",
    "util": "^0.10.4",
    "vm-browserify": "0.0.4"
  },

enter this on terminal export version=0.0.1 and start metro bundler again — Muhammad Numan

In my case, I just added

/*<replacement>*/
var process = require("process");   // THIS LINE
var pna = require('process-nextick-args');
/*</replacement>*/

in node_modules\readable-stream\lib\ _stream_writable.js

looks like it worked for me after installing a few libraries

@ichimaru, you can search for this lines in the whole project and check which of the process variable has not been assigned with a value

Where in the file did you add this? and did you add those 4 lines, or just the line that says "// THIS LINE"...? i've searching for parts of that 4 lines and nothing was found so assume you add all 4 lines, but where about in the file?

This is an old thread and I am not sure if this issue is still existing. Yes only the line says "// THIS LINE"

I am having the issue right now, so it certainly exists in some form or shape. I am building a react native project using multiple modules including crypto (if this helps at all)
