Question

我是一名网络开发人员，我是第一次构建React Native应用程序。该应用程序正在工作和编译，直到我添加了对推送通知的FCM支持。

我使用CocoaPods跟踪了React-Native-FCM的所有说明。

现在，通过内置xCode失败并出现此错误：

clang: error: unable to execute command: Segmentation fault: 11
clang: error: linker command failed due to signal (use -v to see invocation)

我的AppDelegate文件如下所示：

我的PodFile是这样的：

target 'App' do
  use_frameworks!

  # Pods for App
  pod 'Firebase/Core'
  pod 'Firebase/Messaging'

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

end

有没有人遇到过这样的问题？我甚至无法理解导致它的原因（因为错误信息不是很具描述性）

使用通用错误消息，您可能只会获得通用答案。

尝试：

a）删除#define NSFoundationVersionNumber_iOS_9_x_Max 1299以获得提示，就像您的工具链是否正确一样。

b）关闭Xcode 8.1（完全关闭，与cmd + q一样），删除DerivedData文件夹，清空垃圾箱。并且只在最后一步之后重新打开Xcode，才能正确地重新构建缓存。

c）确保您使用的是CocoaPods 1.1.1。毫无疑问，您也可以更新其他工具。示例：sudo gem update -n /usr/local/bin --system && sudo gem update -n /usr/local/bin

d）use_frameworks!之前target，这就是我们通常的做法

e）pod deintegrate && pod install，正确重新整合豆荚

f）最后，克隆你的项目，并尝试从克隆的repo构建：如果它工作，删除旧的repo并使用新的:)。如果它仍然失败，那么您可以开始删除代码段以尝试获取具有最小测试用例的配置，您可以在CocoaPods问题跟踪器上进行共享以进行调查。
