“‘folly/Portability.h”文件未找到React库

Question

在Xcode上遇到构建失败，使用我的react本机项目。错误是'folly/Portability.h' file not found

在过去的几天里，我一直试图自己解决这个问题，但无法解决。

podfile

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
# Required by RNFirebase
pod 'Firebase/Core', '~> 5.20.1'

target 'WhosThat_app' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!
  pod 'Firebase/Firestore'
  pod 'Firebase/Storage'
  pod 'Firebase/Auth'
  pod 'GoogleMaps', '~> 2.7.0'
  pod 'Fabric', '~> 1.10.1'
  pod 'Crashlytics', '~> 3.13.1'
  # Pods for WhosThat_app
  pod 'RNImageCropPicker', :path => '../node_modules/react-native-image-crop-picker'
  pod 'RNBackgroundGeolocation', :path => '../node_modules/react-native-background-geolocation'
  pod 'RNBackgroundFetch', :path => '../node_modules/react-native-background-fetch'
  pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'
  pod 'React', :path => '../node_modules/react-native'
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
  pod 'Folly', podspec: '../node_modules/react-native/third-party-podspecs/Folly.podspec'

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


  end

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

end

尝试移除荚文件夹并重新安装它们，并删除节点模块文件夹。

Answer 1

将以下内容添加到Podfile中的target 'WhosThat_app' do中

target 'WhosThat_app' do

  # ...everything else

  post_install do |installer|
    installer.pods_project.targets.each do |target|
      if target.name == 'React'
        target.remove_from_project
      end
    end
  end

我不需要下面的一行，相信您可以删除它：

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

要解决这个问题，您应该做两件事：

1)添加CxxBridge子规范

2) Point DoubleConversion和glog依赖项直接用于Folly

Podfile示例：

# React Native
rn_path = '../node_modules/react-native'
pod 'React', path: rn_path, subspecs: [
    'CxxBridge',
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket',
    'RCTAnimation',
    'RCTActionSheet',
    'RCTGeolocation',
    'RCTImage',
    'RCTSettings',
    'RCTVibration',
    'RCTLinkingIOS'
]
pod 'yoga', :path => "#{rn_path}/ReactCommon/yoga"
pod 'DoubleConversion', :podspec => "#{rn_path}/third-party-podspecs/DoubleConversion.podspec"
pod 'glog', :podspec => "#{rn_path}/third-party-podspecs/glog.podspec"
pod 'Folly', :podspec => "#{rn_path}/third-party-podspecs/Folly.podspec"

Answer 3

pod 'React', path: rn_path, subspecs: [
  'ART',
  'Core',
  'CxxBridge',
  'RCTText',
  'RCTNetwork',
  'RCTLinkingIOS',
  'RCTImage',
  'RCTAnimation',
  'RCTWebSocket', # needed for debugging
  'RCTActionSheet',
  'RCTGeolocation',
  'RCTSettings',
  'RCTVibration',
  'DevSupport',
  'RCTPushNotification'
]

通过添加这些内容，我的问题得到了成功的解决。
