Cannot read properties of undefined (reading 'transformFile') at Bundler.transformFile

I have updated node today and I'm getting this error:

error: TypeError: Cannot read properties of undefined (reading 'transformFile')
    at Bundler.transformFile (/Users/.../node_modules/metro/src/Bundler.js:48:30)
    at runMicrotasks (<anonymous>)

Other than that I haven't done anything unusual, so I'm not sure what to share. If I'm missing any info please comment and I'll add it.

While building the terminal also throws this error:

My node, npx and react-native versions are:

  • node: 17.0.0
  • npx: 8.1.0
  • react-native-cli: 2.0.1
Solution

  • Ran into the same issue with Node.js 17.0.0. To solve it, I downgraded to version 14.18.1, deleted node_modules and reinstalled.
