react-native start EACCESS error for setup_env.sh

So, I got my first project in ReactNative to run from Windows for Android OS. Took a checkout on a Mac, configured it in an identical manner and as I try to start the react package manager using react-native start and get the following error:

child_process.js:506
    throw err;
    ^
Error: spawnSync /Users/UserName/Desktop/Path/node_modules/react-native/local-cli/setup_env.sh EACCES
    at exports._errnoException (util.js:1022:11)
    at spawnSync (child_process.js:461:20)
    at Object.execFileSync (child_process.js:498:13)

    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

I am aware that it only tries to set the ulimit (open file limit) to 2048 which is permissible for non root users. Also tried running the command with sudo giving it root permissions. Running ulimit -a on the machine revealed an open file limit of 256 and I tried changing the default 2048 to this. Tried increasing it to 4096 as well removing the command altogether. Seems to make no difference what so ever and the error persists.

Created a new project using react-native init DemoProject and the packager seems to start within that folder so the issue is something else?

My package.json is:

{
  "name": "React Native",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "native-base": "^0.5.18",
    "react": "15.4.1",
    "react-addons-shallow-compare": "^15.4.1",

    "react-native-tab-view": "0.0.40",
    "react-redux": "^4.4.6",
    "react-timer-mixin": "^0.13.3",
    "redux": "^3.6.0"
  },
  "devDependencies": {
    "babel-jest": "17.0.2",
    "babel-preset-react-native": "1.9.0",
    "jest": "17.0.3",
    "react-test-renderer": "15.4.1"
  },
  "jest": {
    "preset": "react-native"
  }
}

Also, if it matters I have sinopia, browserify and yarn installed globally.

To start with, I am not sure if I should add all local dependencies through npm yet again on the Mac and then just copy my code or that should be fine and something else is amiss.

It would be great if I can sort this out without re-adding dependencies. Thanks in advance.

Simply had to go to my base project directory and run

chmod -R 777 node_modules
