Expo iOS构建失败求助（SDK 51/React Native 0.74.1）

问题详情 #

使用Expo SDK 51和React Native 0.74.1开发应用，iOS构建持续失败，已尝试以下方法但无效：

• 删除node_modules并执行yarn install
• 降级至Expo SDK 50
• 在AndroidManifest.xml中添加package="com.packageName"

error Failed to build the app: No package name found. We couldn't parse the namespace from neither your build.gradle[.kts] file at /Users/expo/workingdir/build/extra-mobile/node_modules/expo-template-bare-minimum/android/build.gradle nor your package in the AndroidManifest at /Users/expo/workingdir/build/extra-mobile/node_modules/expo-template-bare-minimum/android/app/src/main/AndroidManifest.xml.

 #  -------------------------------------------
Error: Unknown error. See logs of the Install pods build phase for more information.

错误分析 #

1. 包名解析错误：日志显示无法解析node_modules/expo-template-bare-minimum中的Android包名，说明项目中可能残留了该模板的无效依赖，或者初始化时的配置未清理完全。
2. Podfile语法错误：Podfile第21行config = use_native_modules!存在意外token，大概率是react-native-maps的自动生成注释块未正确闭合，导致后续代码语法失效。

解决方案 #

1. 清理无效模板依赖 #

• 打开项目根目录的package.json，查找并移除expo-template-bare-minimum相关依赖项
• 执行yarn install重新安装依赖
• 执行npx expo prebuild --clean清理并重新生成原生配置

2. 修复Podfile语法问题 #

• 打开ios/Podfile，定位到第21行附近的# @generated end react-native-maps注释，确认注释块无语法错误（如未闭合的注释、乱码字符）
• 检查config = use_native_modules!这一行的格式，确保无多余空格、引号或特殊字符
• 若Podfile为自动生成且问题仍存在，可删除ios/Podfile和ios/Podfile.lock，执行npx expo prebuild重新生成Podfile

3. 确认项目包名配置 #

• 确保项目自身的android/app/src/main/AndroidManifest.xml（而非node_modules中的模板文件）包含正确的package属性，如package="com.yourappname"
• 在app.json或app.config.js中配置完整的平台标识符：

  {
    "expo": {
      "ios": {
        "bundleIdentifier": "com.yourappname"
      },
      "android": {
        "package": "com.yourappname"
      }
    }
  }
  

4. 清理构建缓存 #

• 执行npx expo start --clear清理Expo缓存
• 进入iOS目录，执行pod deintegrate && pod install清理Pod依赖并重新安装
