No podspec found for `React-Core` in `../node_modu

Question

I'm using React Native. I get this issue when I try to upload pods. I've successfully installed node_modules, but I'm getting this problem. What is the problem? If we delete the package-lock.json and node_modules folder, I reinstalled npm. But I'm having this problem when I'm doing pod install.

platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target '...' do

Answer 1

Podspec was moved from

../node_modules/react-native/React

to

../node_modules/react-native

So update the line

pod 'React-Core', :path => '../node_modules/react-native/React'

to

pod 'React-Core', :path => '../node_modules/react-native'

Please check it here depend on your react-native version https://react-native-community.github.io/upgrade-helper/?from=0.60.6&to=0.61.4

Answer 2

You should upgrade React Native using react-native upgrade, but check if all pods necessary to your React Native version are in Podfile when upgrading without this tool (sometimes with it too).

One good tool to check Podfile is the Upgrade-helper. For example, if you upgrade RN from 0.60.6 to 0.61.4, RN pod dependencies will be significantly different in Podfile:

# React Native pod dependencies
  pod 'FBLazyVector', :path => "../node_modules/react-native/Libraries/FBLazyVector"
  pod 'FBReactNativeSpec', :path => "../node_modules/react-native/Libraries/FBReactNativeSpec"
  pod 'RCTRequired', :path => "../node_modules/react-native/Libraries/RCTRequired"
  pod 'RCTTypeSafety', :path => "../node_modules/react-native/Libraries/TypeSafety"
  pod 'React', :path => '../node_modules/react-native/'
  pod 'React-Core', :path => '../node_modules/react-native/'
  pod 'React-CoreModules', :path => '../node_modules/react-native/React/CoreModules'

Answer 3

This error occurred as Podspec was moved to

../node_modules/react-native

In order to solve this issue paste the following code in your Podfile. inside your target

 # Pods for RnDiffApp
  pod 'FBLazyVector', :path => "../node_modules/react-native/Libraries/FBLazyVector"
  pod 'FBReactNativeSpec', :path => "../node_modules/react-native/Libraries/FBReactNativeSpec"
  pod 'RCTRequired', :path => "../node_modules/react-native/Libraries/RCTRequired"
  pod 'RCTTypeSafety', :path => "../node_modules/react-native/Libraries/TypeSafety"
  pod 'React', :path => '../node_modules/react-native/'
  pod 'React-Core', :path => '../node_modules/react-native/'
  pod 'React-CoreModules', :path => '../node_modules/react-native/React/CoreModules'
  pod 'React-Core/DevSupport', :path => '../node_modules/react-native/'
  pod 'React-RCTActionSheet', :path => '../node_modules/react-native/Libraries/ActionSheetIOS'

  pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'

I've taken reference from RnDiffApp/ios/Podfile

Make sure not to remove your existing added modules in Podfile.
