Xcode 8.0 中的词法或预处理器问题

Question

我正在使用 react native: 0.41.2、react: 15.4.2 和 cocoapods for firebase(https://github.com/evollu/react-native-fcm)。 我在构建代码时遇到问题。 'React/RCTEventEmitter.h', 'React/RCTBridgeModule.h', 'React/RCTViewManager.h', 'React/RCTDefines.h' 这些文件未找到错误在运行项目时抛出.

但是通过使用该文件名单击 ctrl，这些文件已经在我的项目中。 Image

podfile：

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
source 'https://github.com/CocoaPods/Specs.git'

target 'Inspector' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for Inspector
  react_native_path = "../node_modules/react-native"
  pod "React", :path => react_native_path, :subspecs => [
    'Core',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTGeolocation',
    'RCTImage',
    'RCTLinkingIOS',
    'RCTNetwork',
    'RCTSettings',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket'
  ]
  pod 'Firebase/Core'
  pod 'Firebase/Messaging'
  target 'Inspector-tvOSTests' do
    inherit! :search_paths
    pod 'Firebase/Messaging'
    # Pods for testing
  end

  target 'InspectorTests' do
    inherit! :search_paths
    pod 'Firebase/Messaging'
    # Pods for testing
  end

end

Answer 1

对于那些面临这个问题的人，这是由于 react native 0.41.2 和 cocoapods 的标头导入问题 要解决这些错误，请按照以下步骤操作

1npm install -g react-native-git-upgrade

2 转到您的项目根文件夹并执行

react-native-git-upgrade

3 升级RN时出现冲突解决

4 现在从 pod 文件中删除 React 依赖项，否则您将有两个 React 方案（一个 RN 和一个 Pod），它将在构建时导致 no input error。您的 pod 文件应如下所示

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
source 'https://github.com/CocoaPods/Specs.git'

target 'Inspector' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for Inspector   // Pods for your app, in this case firebase is used
  pod 'Firebase/Core'
  pod 'Firebase/Messaging'
  target 'Inspector-tvOSTests' do
    inherit! :search_paths
    pod 'Firebase/Messaging'
    # Pods for testing
  end

  target 'InspectorTests' do
    inherit! :search_paths
    pod 'Firebase/Messaging'
    # Pods for testing
  end

end

5 cd ios && pod 安装

6 关闭 Xcode 并打开 .xcworkspace 文件
