React native ios - 运行 pod install 时出错（安装 Flipper-Glog）

Question

当我尝试运行 pod install 时，程序到达 Installing Flipper-Glog (0.3.6) 时会产生错误
以下是完整的错误消息：

Installing Flipper-Glog (0.3.6)

if [ -z "$CURRENT_ARCH" ] || [ "$CURRENT_ARCH" == "undefined_arch" ]; then
    # Xcode 10 beta sets CURRENT_ARCH to "undefined_arch", this leads to incorrect linker arg.
    # it's better to rely on platform name as fallback because architecture differs between simulator and device

我正在使用 react native 0.63.3 ...下面是我的 podfile：

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '10.0'

target 'xs' do
  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])

  permissions_path = '../node_modules/react-native-permissions/ios'
  pod 'Permission-Notifications', :path => "#{permissions_path}/Notifications/Permission-Notifications.podspec"
  pod 'Permission-Camera', :path => "#{permissions_path}/Camera/Permission-Camera.podspec"
  pod 'Permission-LocationAlways', :path => "#{permissions_path}/LocationAlways/Permission-LocationAlways.podspec"
  pod 'Permission-LocationWhenInUse', :path => "#{permissions_path}/LocationWhenInUse/Permission-LocationWhenInUse.podspec"
  pod 'Permission-PhotoLibrary', :path => "#{permissions_path}/PhotoLibrary/Permission-PhotoLibrary.podspec"
  pod 'Permission-MediaLibrary', :path => "#{permissions_path}/MediaLibrary/Permission-MediaLibrary.podspec"

  pod 'GoogleMaps'
  pod 'Google-Maps-iOS-Utils'
  
  pod 'RNSound', :path => '../node_modules/react-native-sound'

  target 'xsTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)
  end
end

更新 2/21 如果你在 Podfile 中注释掉下面的代码......那么构建会更进一步（因为它没有安装 Flipper-Glog）......但它反而在 Installing glog (0.3.5) 失败

# use_flipper!()
# post_install do |installer|
#   react_native_post_install(installer)
# end

查看堆栈跟踪，出现以下错误：

xcrun: error: SDK "iphoneos" cannot be located
xcrun: error: unable to lookup item 'Path' in SDK 'iphoneos'

Answer 1

在我的问题更新中注释掉脚蹼代码后....下面 2 个答案的组合解决了我的问题：
Xcode, Pods ProjectName.debug.xcconfig unable to open file. Wrong directory （@pragmus 回答）
xcrun: error: SDK "iphoneos" cannot be located（@Karrar Al-Mimar 回答）

Answer 2

在我的例子中，这个错误与命令行工具配置有关。我只是选择我的 Xcode 版本作为解释 React Native 在他们的文档 https://reactnative.dev/docs/environment-setup

Xcode > 首选项 > 位置 > 命令行工具

Answer 3

在我的情况下，只需在 Xcode 设置上选择命令行工具，它就会修复。

1. 单击工具栏左上角的 Xcode。

2. 点击偏好

3. 点击位置

4. 选择命令行工具（它不应该为空。在我的情况下它是空的。一旦我选择版本然后问题解决。）
