NativeScript iOS 构建失败 Xcode - 错误：命令 Ld 失败，退出代码为非零

Question

我浪费了大量时间尝试为 iOS 构建 NativeScript 项目。我一直在开发移动 NativeScript 应用程序一段时间，但由于我主要使用 Windows，直到现在我只能在 Android 上进行测试。我终于把我的 Macbook 拿出来在 iOS 设备上试用我的 NativeScript Angular 应用程序，但我遇到了麻烦。

我什至尝试启动一个全新的 helloworld 项目 ns create myapptest 和 ns run ios --no-hmr 我仍然得到一个失败的构建并且错误报告并没有真正帮助。我已经搜索并尝试了很多没有运气的东西。一切都更新到最新版本。 Cli 显示错误 Command xcodebuild failed with exit code 65. 和 Xcode 12 显示 Command Ld failed with a nonzero exit code 两者都没有太大帮助，但在链接阶段似乎出现了问题。我什至尝试了 Xcode 11.7 和 Xcode 12.3-Beta，但仍然遇到相同的错误。我在下面粘贴了 Xcode 12 的错误输出，这是一个 pastebin 链接 https://pastebin.com/Y2RpAmTE，其中包含 ns build ios --release --log trace 的完整日志跟踪。

奇怪的是，我确实有一个项目可以在 iOS 设备上运行。这是来自@EddyVerbruggen https://github.com/eddyverbruggen/nativescript-barcodescanner 的nativescript-barcodescanner 的演示，我能够打开Xcode 项目文件并在物理iOS 设备上构建/运行它。我找不到那个演示项目和来自 CLi 的新 HelloWorld 项目之间的区别。

有人可以帮忙吗？感谢您的宝贵时间，我真的很感激！

复制： ns create myapptest && ns run ios --no-hmr

预期行为： 为 iOS 设备和模拟器成功构建应用

示例项目： 默认 NativeScript Cli HelloWorld 项目

Xcode 的错误输出：

Answer 1

我终于明白了！我认为这与使用带有 dosdude1 修补程序的 Mac 在不受支持的 Mac 上运行 macOS Catalina 有关。我让它工作的方式是自己编译元数据生成器：

• 下载 LLVM 8.0 http://releases.llvm.org/download.html#8.0.0 （直接下载：https://releases.llvm.org/8.0.0/clang+llvm-8.0.0-x86_64-apple-darwin.tar.xz） 并确保在 PATH 中有包含 llvm-config 的文件夹或在 /usr/local/bin/ 中建立符号链接
• 下载并安装 Cmake https://cmake.org/download/ （注意：如果您使用 dosdude1 的补丁来运行 macOS Catalina，请勿使用自制软件安装 LLVM 和 Cmake，我在自制软件安装具有不兼容二进制文件的软件时遇到了问题，这会出现 zsh：非法硬件指令所以请注意安全并使用上面的链接下载。）
• git clone https://github.com/NativeScript/ns-v8ios-runtime
• cd ns-v8ios-runtime
• ./build_metadata_generator.sh 这将在ns-v8ios-runtime/metadata-generator/bin 中构建objc-metadata-generator 您需要在接下来的步骤中复制并粘贴整个bin 文件夹。
• 现在转到您的 NativeScript 项目目录（我将其命名为 demo-app） cd demo-app
• 如果您还没有，请为 iOS 准备项目ns prepare ios
• 现在您将用我们刚刚在几步前编译的objc-metadata-generator 替换不工作的objc-metadata-generator。首先我们将删除现有的bin 文件夹，然后将我们新编译的bin 文件夹复制到它的位置。 rm -R platforms/ios/internal/metadata-generator/bin
• 现在复制我们从ns-v8ios-runtime/metadata-generator/bin 编译的bin 文件夹并将其粘贴到您的项目中，demo-app/platforms/ios/internal/metadata-generator/bin
• ns run ios --no-hmr

您的项目现在应该可以在 iOS 上运行了！希望这对某人有所帮助，它对我有用。请注意，无论何时您ns platform remove ios，您都需要将项目中的bin 文件夹替换为您自己编译的文件夹。祝你好运！
