  end

  target 'WhosThat_appTests' do

  end

end

尝试删除 pods 文件夹并重新安装它们并删除 node-modules 文件夹

Answer 1

以下添加到您的Podfile内部target 'WhosThat_app' do ：

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

我不需要以下行，并且相信您可以将其删除：

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

• 解决方案适用于 React Native 版本59 。

要解决此问题，您应该做两件事：

1) 添加CxxBridge 子规范

2) 直接为Folly指向DoubleConversion和glog依赖项规范

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，我的问题已成功解决。
