Rn-fetch-blob: Unable to run pod install and React Native link is throwing warning.

[waqas19921]

I have used following versions
React Native version = 0.60.0-rc.3
Fetch Blob version = 0.10.15

react-native link command is giving following warning on new react-native version 0.60.

RNFB_ANDROID_PERMISSIONS=true react-native link rn-fetch-blob
warn Package "rn-fetch-blob" is using deprecated "rnpm" config that will stop working from next release. Please notify its maintainers about it.

Need to update pod dependencies for new version of react-native.

Here is the stack when i ran pod install

[!] CocoaPods could not find compatible versions for pod "React/Core":
  In Podfile:
    rn-fetch-blob (from `../node_modules/rn-fetch-blob`) was resolved to 0.10.6, which depends on
      React/Core

None of your spec sources contain a spec satisfying the dependency: `React/Core`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

Same issue here, any idea how to fix it?

The same thing is happening to me. If anyone has any idea how to solve this...

We need to apply https://github.com/Soni96pl/react-native-sound/commit/c8034526893f4f7f5463fa53e0ce5875cfbde845 to https://github.com/joltup/rn-fetch-blob/blob/master/rn-fetch-blob.podspec.

Problem is, the PR will never be merged, AndroidX PR is pending since 01/24 :/

I'm going to use patch-package to apply Fouppy's fix until, hopefully, there is an update to this dependency.

nice, that worked for me and i guess it is a quite good workaround while so many the RN60 PRs are still waiting to be merged
