[!] Unable to find a specification for React-Core depended upon by RNPermissions

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• out-of-date source repos which you can update with pod repo update or with pod install --repo-update.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've same issue

[Ashishlog9]

I am suffering from this issue since three days . its like hell

[deejayxd07]

Try adding this on your Podfile:

  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])

Like so:

target 'yourAppNameHere' do
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways.podspec"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse.podspec"

  target 'yourAppNameHereTests' do
    inherit! :complete
    # Pods for testing
  end

  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])
end

[Ashishlog9]

After adding this i am getting syntax error ;

[!] Invalid Podfile file: syntax error, unexpected keyword_end, expecting end-of-input.

from /Users/728583/Desktop/reactworkspace/MA_new326_1/ESA/ios/Podfile:124

-------------------------------------------

use_react_native!(:path => config[rn_path])

end

[Ashishlog9]

See the error i got
[!] Invalid Podfile file: undefined method `use_native_modules!' for #Pod::Podfile:0x00007f9232beb970
Did you mean? use_modular_headers!.

I had to change "react-native-permissions": "^2.0.0" to "react-native-permissions": "2.0.0" in my package.json. And removed node_modules then npm install. I ran the pod install. It worked.
PS: Make sure you have this pod 'RNPermissions', :path => '../node_modules/react-native-permissions' in your Podfile.

[ZakeryFyke]

I fixed this by opening the podspec file for react native permissions (in the node modules folder, under react-native-permissions, called RNPermissions.podspec) and replacing the line

s.dependency "React-Core"

with

s.dependency "React/Core"

[ketan-kumar]

Uninstalled node_modules and rebuilding pods worked for me.
