Flutter问题：无法在iPhone Simulator安装Runner.app - Error 149

问题详情 #

使用flutter run命令在iPhone Simulator上运行Flutter应用时，出现安装失败错误，具体日志如下：

Unable to install /Users/enkh-amgalan/Desktop/lesson/mobile/week-1/add_sub_app/build/ios/iphonesimulator/Runner.app on 524B6B86-9413-48BF-9408-288F75BDC9F4.
This is sometimes caused by a malformed plist file:

解决步骤 #

• 重启CoreSimulator服务与模拟器

  1. 关闭所有运行的iPhone Simulator窗口
  2. 终端执行命令强制重启CoreSimulator服务：

     killall -9 com.apple.CoreSimulator.CoreSimulatorService
     

  3. 重新打开模拟器，执行flutter run重试

• 重置模拟器数据

  1. 在模拟器顶部菜单选择Device → Erase All Content and Settings...，确认重置
  2. 清理项目缓存后重新构建：

     flutter clean
     flutter pub get
     flutter run
     

• 检查Xcode与环境配置

  1. 确保Xcode为最新稳定版，打开Xcode设置→Locations，确认Command Line Tools已选中当前Xcode版本
  2. 执行flutter doctor检查Flutter环境是否存在异常，修复提示的问题

• 验证Info.plist文件

  1. 打开项目路径ios/Runner/Info.plist
  2. 检查文件是否存在语法错误，确认CFBundleIdentifier、CFBundleName等必填字段完整且格式正确
