React-native: Unable to find a specification for `React-Core (= 0.63.0)` depended upon by `React`

[waheedakhtar694]

I have upgraded my react-native version from 0.62.2 to 0.63.0 with upgrade helper but after that when I try to install pods getting this error.

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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.

I'm getting the same issue, with a different resource.

[!] CocoaPods could not find compatible versions for pod "ReactCommon/callinvoker":
  In Podfile:
    ReactCommon/callinvoker (from `../node_modules/react-native/ReactCommon`)

None of your spec sources contain a spec satisfying the dependency: `ReactCommon/callinvoker (from `../node_modules/react-native/ReactCommon`)`.

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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.

@enaluz I manage to fix this issue, Actually it was my bad, I missed to add
use_react_native!(:path => config["reactNativePath"]) in pod file.

[waheedakhtar694]

@enaluz If it is fix for you, can I close it?

Where you able to resolve this? I am getting the same error

[PaulGoodDay]

use_react_native

Where does this go in the Podfile?

[SNikon]

@PaulGoodDay

target 'YourProject' do
   use_react_native!
   (...other stuff may be here)
end

use_react_native!(:path => config["reactNativePath"]) in pod file.

That should be right answer.
Thank you so much.
