我是一名网络开发人员，我是第一次构建 React Native 应用程序。 在我为推送通知添加 FCM 支持之前，该应用程序一直在运行和编译。

我遵循了 React-Native-FCM 中的所有说明, 使用 CocoaPods。

现在在 xCode 中构建失败并出现以下错误:

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

有人遇到过这样的问题吗？我什至不明白是什么原因造成的(因为错误消息的描述性不强)

最佳答案

对于一般性的错误消息，您可能只会得到一般性的答案。

尝试:

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

b) 关闭 Xcode 8.1(完全关闭，就像使用 cmd+q)，删除 DerivedData 文件夹，清空垃圾箱。并且只有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! 在 target 之前，我们通常就是这样做的

e) pod deintegrate && pod install，正确地重新集成 pod

f) 最后，克隆你的项目，并尝试从克隆的 repo 构建:如果可行，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片段以尝试获得具有最小测试用例的配置，您可以在 CocoaPods 问题跟踪器上共享该配置以供调查。
