Why if I run npm install using react-native "0.63.2" build the libraries with extension podspec

I try to run a react-native project in Xcode and I use cocoapods for entities but I have some problems with the libraries in xcode, all the libraries have color red, that's mean that files there aren't in whole project

example libraries React.xcodeproj, RCTAnimation.xcodeproj, RCTActionSheet.xcodeproj, RCTBlob.xcodeproj, RCTGeolocation.xcodeproj, RCTImage.xcodeproj, RCTLinking.xcodeproj, RCTNetwork.xcodeproj, RCTSettings.xcodeproj, RCTText.xcodeproj, RCTVibration.xcodeproj, RCTWebSocket.xcodeproj.

I seek in directory /Users/mac/Apps/ReactNativeVideoChatApp-2/MessengerApp/node_modules/react-native/LiLibraries but just find libraries like React-RCTVibration.podspec with extension .podspec

that's happen when I run npm install in the project using react-native 0.63.2 but if I use react-native 0.58.1. just for try with other version appear the libraries with extension .xcodeproject but if I try to run pod install or pod update the terminal show next message [!] Invalid Podfile file: cannot load such file.

I tried to run project with version react-native 0.63.2 but the libraries have extension podspec and Xcode don't recognize.
