CocoaPods 找不到 pod "React/Core" 的兼容版本？

Question

按照链接中的步骤将 react native 集成到现有项目中没有帮助。

链接： https://reactnative.dev/docs/integration-with-existing-apps

配置

Mac OS X - 10.15.6 (19G2021)
XCode - 12.1 (12A7403)
React Native Cli - 2.0.1
React Native - 0.63.4

package.json

{
  "name": "MyReactNativeApp",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "yarn react-native start"
  }
  "dependencies": {
    "react-native": "^0.63.4"
  }
}

Podfile

source 'https://github.com/CocoaPods/Specs.git'

# Required for Swift apps
platform :ios, '11.0'
use_frameworks!

# The target name is most likely the name of your project.
target 'MyReactNativeApp' do
  
  # Your 'node_modules' directory is probably in the root of your project,
  # but if not, adjust the `:path` accordingly
  pod 'React', :path => '../MyReactNativeApp/node_modules/react-native', :subspecs => [
  'Core',
  'CxxBridge', # Include this for RN >= 0.47
  'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
  'RCTText',
  'RCTNetwork',
  'RCTWebSocket', # needed for debugging
  # Add any other subspecs you want to use in your project
  ]
  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod "Yoga", :path => "../MyReactNativeApp/node_modules/react-native/ReactCommon/yoga"
  
  # Third party deps podspec link
  pod 'DoubleConversion', :podspec => '../MyReactNativeApp/node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
  pod 'glog', :podspec => '../MyReactNativeApp/node_modules/react-native/third-party-podspecs/glog.podspec'
  pod 'Folly', :podspec => '../MyReactNativeApp/node_modules/react-native/third-party-podspecs/Folly.podspec'
  
end

当我运行 pod install 时。我收到一个错误

[!] CocoaPods could not find compatible versions for pod "React/Core":

截图：

我检查了现有的线程。没有什么可以正常工作。我还做了 pod 'React' 移除了其他所有东西，结果是

1. 已弃用
2. 它未被检测为模块。未找到模块 - 我 将为此分开问题。

按照以下步骤操作。这可能会有所帮助。

• 在 XCode 中打开您的项目。
• 展开Pods文件。
• 应该有Development Pods，也展开。
• 找到React 文件夹。应该有 2 个文件夹：Pods 和 Support Files。转到Pods 文件夹。
• 这个目录应该包含React.podspec文件，打开它，找到s.dependency "React/Core",在哪里，改成s.dependency "React-Core",。
