Rebuild the app

[russelRajitha]

the same issue is getting with a fresh installation: the latest RN and this library version.

I got this issue while using expo prebuild and rebuilding the app fixed it. You can also try manually linking the library.

I downgrade RN to "0.69.5" and issue has resolved

This is an obsolete package. Use this https://github.com/RonRadtke/react-native-blob-util

I resolved it by rebuilding the app, and make sure to add this code to your Podfile if you're using CocoaPods.

pod 'rn-fetch-blob',
    :path => '../node_modules/rn-fetch-blob'

rn-fetch-blob: 0.13.0-beta.2 is it install and solve problem

You just need to terminate current process and rebuild your app after installing rn-fetch-blob then this error will be resolved

So, its better to restart vscode or the editor you are using after installing rn-fetch-blob package
