架构x86_64

Question

我最近在react-native-maps遇到一个奇怪的问题。尝试通过xcode编译应用程序时，出现以下错误

...
ld: 1159 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Whole stacktrace

到目前为止，我已经尝试了所有方法。例如，这些帖子first second

这是我的Podfile：

platform :ios, '9.0'
source 'https://github.com/CocoaPods/Specs.git'

target "__APP_NAME__" do
  react_native_path = "../node_modules/react-native"
  pod "yoga", :path => "#{react_native_path}/ReactCommon/yoga"
  pod 'React', path: '../node_modules/react-native', :subspecs => [
  'Core',
  'RCTActionSheet',
  'RCTGeolocation',
  'RCTImage',
  'RCTLinkingIOS',
  'RCTNetwork',
  'RCTSettings',
  'RCTText',
  'RCTVibration',
  'RCTWebSocket'
  ]

  pod 'GoogleMaps'

  pod 'Firebase/Core', '~> 5.3.0'
  pod 'Firebase/Messaging', '~> 5.3.0'

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == 'react-native-google-maps'
      target.build_configurations.each do |config|
        config.build_settings['CLANG_ENABLE_MODULES'] = 'No'
      end
    end
    if target.name == "React"
      target.remove_from_project
    end
  end
end

我还尝试使用react-native-maps存储库中自述文件中指定的完全相同的Podfile（具有相同的结果），并且还尝试从{{1 }}，这导致了应用程序的构建，但是当我尝试启动它时，main.m文件中的-ObjC崩溃了。

编辑：

在安装Other Linker Flags之前，我已将git repo还原为重新安装所有节点模块，并尝试重新安装所有pod（我运行this和Thread 1: signal SIGABRT），然后尝试重建xcode中的项目，仍然出现相同的错误。我的Podfile

react-native-maps

我现在想知道，我的项目出了什么问题？

Answer 1

因此，经过大约整天的调试，我发现了该应用无法构建的原因。如果我在发布此答案之前没有解决问题，则@Christos Koninis的评论将使我找到问题的根本原因。我再次查看了日志，发现我一直在使用React的两个实例。一个来自node_modules/，另一个来自ios/pods/。我所缺少的是我的Podfile中的内容：

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

最后，我的Podfile如下：
