• react-native-google-mobile-ads: ^9.1.1

报错信息 #

023-02-07 23:05:06.067 xcodebuild[92292:1835009] [MT] IDEFileReferenceDebug: [Load] <IDESwiftPackageCore.IDESwiftPackageSpecialFolderFileReference, 0x7fa23ae8f960: name:Docs.docc path:group:Docs.docc> Failed to load container at path: /Users/sangnlee/Library/Developer/Xcode/DerivedData/aaa-csqwegbowuhmbrehpztorwqemvkb/SourcePackages/checkouts/swift-protobuf/Sources/protoc-gen-swift/Docs.docc, Error: Error Domain=com.apple.dt.IDEContainerErrorDomain Code=6 "Cannot open "Docs.docc" as a "Swift Package Folder" because it is already open as a "Folder"." UserInfo={NSLocalizedDescription=Cannot open "Docs.docc" as a "Swift Package Folder" because it is already open as a "Folder".}
** BUILD FAILED **

The following build commands failed:
Ld /Users/aaa/Library/Developer/Xcode/DerivedData/aaa-csqwegbowuhmbrehpztorwqemvkb/Build/Products/Debug-iphonesimulator/aaa.app/aaa normal (in target 'aaa' from project 'aaa')
(1 failure)

解决步骤 #

1. 清理Xcode DerivedData #

直接删除报错关联的DerivedData文件夹，两种操作方式：

• 图形化操作：打开Xcode → 菜单栏Xcode > Preferences > Locations → 点击DerivedData路径后的箭头打开文件夹，删除当前项目对应的DerivedData文件夹
• 命令行操作：

rm -rf ~/Library/Developer/Xcode/DerivedData/aaa-csqwegbowuhmbrehpztorwqemvkb

2. 重置CocoaPods依赖 #

进入项目ios目录执行以下操作：

cd ios
rm -rf Pods Podfile.lock
pod install --repo-update

3. 解决Swift Package Manager冲突 #

这个报错大概率是swift-protobuf包重复引用导致的，按以下步骤处理：

• 打开Xcode → 菜单栏File > Packages > Reset Package Caches
• 检查项目中是否手动添加过swift-protobuf，如果有直接移除（react-native-google-mobile-ads已自带该依赖）
• 也可以在Podfile中指定固定版本避免冲突：

pod 'SwiftProtobuf', '~> 1.21.0'

4. 重置Xcode项目状态 #

• 关闭Xcode
• 删除项目的xcuserdata文件夹：

rm -rf ios/aaa.xcodeproj/xcuserdata

• 重新打开项目，按Command + Shift + K清理构建缓存，再重新编译

5. 调整依赖版本 #

如果以上步骤无效，尝试调整依赖版本：

• 查阅react-native-google-mobile-ads官方文档，确认与RN 0.71.1兼容的版本，尝试升级或降级该包
• 比如降级到^8.0.0版本，再重复上述清理步骤重新构建
