npm start not working for react native setup

Hei, I'm new to programming and trying to Setup my toolchain and create a new React Native project.

  • If needed, install code editor (+ extensions), git, npm
  • Install the Expo app to your phone. iOS or Android
  • Use the expo CLI tool to generate an app skeleton
  • Create a folder for your React Native projects
  • use Git Bash or terminal to go to this folder cd foldername/otherfoldername/etc...
  • npm install -g expo-cli
  • expo init MyApp --npm
  • choose 'blank' template
  • if this fails on Windows due to missing interactive mode, use cmd instead of Git Bash Test that app works; run it and open in the browser (the interactive shell is needed to get the menu option (w) for launching in browser)
  • cd MyApp
  • npm start <---
  • From now on open 'MyApp' folder in your editor/IDE to edit your project Create a remote git repository (Github) and push your app there

I have done these but I get this error when I write in my VScode npm run

  • expo start

  • Starting project at C:\Users\35845\Documents\ReactNativeProject\MyApp

  • Expo DevTools is running at http://localhost:19002

  • Opening DevTools in the browser... (press shift-d to disable)

  • Error: spawn powershell ENOENT

  • at Process.ChildProcess._handle.onexit (internal/child_process.js:240:19)

  • at onErrorNT (internal/child_process.js:415:16)*     at process._tickCallback (internal/process/next_tick.js:63:19)

  • npm ERR! code ELIFECYCLE

  • npm ERR! errno 1

  • npm ERR! @ start: expo start

  • npm ERR! Exit status 1

  • npm ERR!

  • npm ERR! Failed at the @ start script.

  • npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

  • npm ERR! A complete log of this run can be found in:

  • npm ERR! C:\Users\35845\AppData\Roaming\npm-cache_logs\2020-08-26T08_53_44_736Z-debug.log

Can someone please help me with this. Thank you

use cmd instead of git bash or PowerShell on windows and try below steps and run:-

Delete node_modules folder
run npm cache clean --force
npm install
expo start

make sure you are inside your application folder (where package.json is present)
