无法在 React Native 0.60.3 上安装 react-native-unimodules

Question

安装 yarn install react-native-unimodules

说明中的下一步要求我编辑我的项目 Podfile。必要的添加是 shown here.

这是我生成的 Podfile

platform :ios, '10.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
require_relative '../node_modules/react-native-unimodules/cocoapods.rb'
target 'MyProjectName' do
  # Pods for MyProjectName
  pod 'React', :path => '../node_modules/react-native/', :subspecs => [
    'Core',
    'CxxBridge',
    'DevSupport',
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket',
    'RCTAnimation',
    'RCTImage',
  ]
  pod 'React-Core', :path => '../node_modules/react-native/React'
  pod 'React-DevSupport', :path => '../node_modules/react-native/React'
  pod 'React-fishhook', :path => '../node_modules/react-native/Libraries/fishhook'
  pod 'React-RCTActionSheet', :path => '../node_modules/react-native/Libraries/ActionSheetIOS'
  pod 'React-RCTAnimation', :path => '../node_modules/react-native/Libraries/NativeAnimation'
  pod 'React-RCTBlob', :path => '../node_modules/react-native/Libraries/Blob'
  pod 'React-RCTImage', :path => '../node_modules/react-native/Libraries/Image'
  pod 'React-RCTLinking', :path => '../node_modules/react-native/Libraries/LinkingIOS'
  pod 'React-RCTNetwork', :path => '../node_modules/react-native/Libraries/Network'
  pod 'React-RCTSettings', :path => '../node_modules/react-native/Libraries/Settings'
  pod 'React-RCTText', :path => '../node_modules/react-native/Libraries/Text'
  pod 'React-RCTVibration', :path => '../node_modules/react-native/Libraries/Vibration'
  pod 'React-RCTWebSocket', :path => '../node_modules/react-native/Libraries/WebSocket'

  pod 'React-cxxreact', :path => '../node_modules/react-native/ReactCommon/cxxreact'
  pod 'React-jsi', :path => '../node_modules/react-native/ReactCommon/jsi'
  pod 'React-jsiexecutor', :path => '../node_modules/react-native/ReactCommon/jsiexecutor'
  pod 'React-jsinspector', :path => '../node_modules/react-native/ReactCommon/jsinspector'
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

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

  target 'MyProjectNameTests' do
    inherit! :search_paths
    # Pods for testing
  end

  use_native_modules!
end

target 'MyProjectName-tvOS' do
  # Pods for MyProjectName-tvOS

  target 'MyProjectName-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

下一步是运行 pod install，它给出以下 output/error：

$ pod install

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

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

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.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

根据对 Github issue regarding this exact error output 的回复，我搜索了整个项目目录的文件内容，但没有找到任何地方 React-Core 可能被错误定义为 React/Core.

这是我第一次编辑 Podfile，我担心我可能在语法上犯了错误。

Answer 1

React Native changed a lot of things in 0.60, one of them was to split React podspec into separate podspecs.

这意味着 React podspec 不再有任何 subspecs。您得到的错误是 React/Core，它曾经是一个子规范，不再可用（现在单独导入）。要解决此问题，请从 Podfile:

中删除 subspecs

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

请注意，您可以在网络上找到许多教程和文档，其中包含 subspecs 定义。这就是 React Native <=0.59 中的做法，在 0.60 中不再有效。

Answer 2

我猜 podspec 名称已更改：React-Core 不在子文件夹中，它在根文件夹中。这是我的工作 pod 文件 React-Native 0.61.3:
