来源：使用 Cocoapods for Firebase 时出现未绑定变量错误

Question

我已使用 Cocoapods 将 Firebase 和 GoogleTagManager 集成到我的 iOS 应用程序目标中。 当我构建我的目标时，Xcode 不断地给我错误：

Showing Recent Messages
PhaseScriptExecution [CP]\ Embed\ Pods\ Frameworks 

mkdir -p /Users/xxx.xxx/Library/Developer/Xcode/DerivedData/MyApp-enzvpdzsyhjszqbnwiclnpszlyri/Build/Products/Debug-iphonesimulator/MyApp.app/Frameworks


/Users/xxx.xxx/Projects/MyApp/Applications/MyApp/Pods/Target Support Files/Pods-MyApp/Pods-MyApp-frameworks.sh: line 43: source: unbound variable


Command /bin/sh failed with exit code 1

我已经多次清理我的项目，删除了派生数据文件夹，但这些似乎都不起作用。

我的 Podfile 如下所示：

platform :ios, '11.0'

target 'MyApp' do

  use_frameworks!

  # Pods for MyApp
    pod 'Firebase/Core', '~> 5.19'
    pod 'Firebase/ABTesting'
    pod 'Firebase/Performance'
    pod 'Firebase/RemoteConfig'
    pod 'Firebase/Analytics'
    pod 'GoogleTagManager', '~> 7.1'
 end

Cocoapods 环境

CocoaPods : 1.5.3
        Ruby : ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-darwin16]
    RubyGems : 2.6.8
        Host : Mac OS X 10.14 (18A391)
       Xcode : 10.1 (10B61)
         Git : git version 2.17.2 (Apple Git-113)
Ruby lib dir : /Users/xxx.xxx/.rbenv/versions/2.4.0/lib
Repositories : master - https://github.com/CocoaPods/Specs.git @ 7c9a708dce25221eabc35ed39

我的项目设置中缺少什么导致此错误？

我花了几天时间寻找关于 SO / Cocoapods 的解决方案，但徒劳无功。

非常感谢您在这方面的任何帮助。

谢谢

这似乎是一些特殊的问题，可能与 bash 相关或其他什么。由于某些奇怪的原因，它不适用于 ~/Library/.../MyApp-xxxxx.../Build/Products/Release-iphoneos/ 目录（我们称之为 BUILD_DIR）

如果 'source' 未定义（这里就是这种情况），将 ${source} 替换为 ${source:-} 并没有帮助，因为它会为 source 放置一个空白，这不是您想要的。

对我来说另一个问题是 rsync 没有找到上面的目录。

这是我所做的：

1. 让项目构建并给出错误。这样可以确保在我的 BUILD_DIR 中创建所需的框架目录，并构建框架。

2. 在项目根目录下创建了一个Pods-frameworks目录，将BUILD_DIR中的所有framework目录复制到这个目录中。

3. 在 PodsMyApp-frameworks.sh 的最后 25 行中，调用 install_framework 以及处于调试和发布模式的所有 pod 相关框架，将 ${BUILT_PRODUCTS_DIR} 更改为定义为这个新 Pods-frameworks 目录的新宏。

4. 再次构建项目。

这解决了问题。如果再次安装 pods 并且版本发生更改，则可能需要重复此过程。

好吧，这个问题我搞砸了4天，终于用脚本解决了。

设置

• RN 0.61.5 从 0.59.10 升级
• Xcode 11.3.1
  • 多方案（暂存，测试版）
  • 多配置（暂存，测试版）

相关的 npm 包：

    "react-native": "0.61.5",
    "@react-native-firebase/app": "^8.4.6",

  end

  use_native_modules!
end

此设置是2016年以来一个项目逐步开发的结果，所以项目和实际配置不推荐，最好从头开始！

导致此问题的步骤，所有步骤都无法生成 beta 存档：

1. 通过升级命令升级rn
2. 使用RN Upgrade helper 修补命令丢失的文件
3. 使用上面提到的来自 Code Push 的 guide 创建 Xcode 配置
4. 未知...

在旅途中的某个地方，我最终得到了 PODS_CONFIGURATION_BUILD_DIR 构建设置，该设置具有 ${PODS_BUILD_DIR}/Release$(EFFECTIVE_PLATFORM_NAME) for Beta configuration

此时正在运行 Beta 构建，但归档失败并显示 source: unbound variable

每当我将PODS_CONFIGURATION_BUILD_DIR 更改为${PODS_BUILD_DIR}/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME) 或者如果我编辑出Podfile 修复相同的PODS_CONFIGURATION_BUILD_DIR 更改构建阶段失败

'React/RCTBridgeDelegate.h' file not found.

通过...frameworks.sh 挖掘很明显Pods 构建输出到Release-iphoneos 文件夹，而由于PODS_CONFIGURATION_BUILD_DIR 设置或类似设置，其余部分在Beta-iphoneos 中，我尝试更改为默认值，但是然后构建甚至在到达这个构建阶段之前就失败了[CP] Embed Pods Frameworks

最后，我只是在此阶段之前使用以下脚本将所有内容从 Release-iphoneos 移动到 Beta-iphoneos：

+ New Run Script Phase

# Type a script or drag a script file from your workspace to insert its path.
if [[ "$CONFIGURATION" == "Debug" ]]; then
    exit 0
elif [[ "$CONFIGURATION" == "Release" ]]; then
    exit 0
fi

mv $BUILD_DIR/Release$EFFECTIVE_PLATFORM_NAME/* $BUILD_DIR/$CONFIGURATION$EFFECTIVE_PLATFORM_NAME/

在这里有点累，只是想它可能会帮助有类似情况的任何人，希望我能提供更多帮助，欢迎反馈。

当我的框架使用 M1 芯片构建时，我遇到了同样的问题。 我可以通过从 Podfile 安装程序部分中删除 ONLY_ACTIVE_ARCH 来解决这个问题。

所以我替换了这个：

post_install do |installer|

installer.pods_project.targets.each do |target|

target.build_configurations.each do |config|
  config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
  config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'

 end
end

有了这个：

post_install do |installer|

installer.pods_project.targets.each do |target|

target.build_configurations.each do |config|
  config.build_settings['BUILD_LIBRARY_FOR_DISTRIBUTION'] = 'YES'
 end
end

注意：我从一开始就添加了 ['ONLY_ACTIVE_ARCH'] = 'NO'，以便在使用非 M1 芯片构建框架时使用“有问题的”框架在模拟器中运行我的应用程序。 所以我还是需要这条线，具体取决于构建机的芯片。
