执行flutter build appbundle构建AppBundle失败 无法打开输出文件如何解决

执行flutter build appbundle命令构建AppBundle安装包时，构建流程无法正常启动，抛出如下错误信息：

Failed to open output file 'F:\Mobile app\user app\booking_system_flutter\booking_system_flutter\build\app\intermediates\flutter\release\flutter_assets\packages/flutter_vector_icons/fonts/AntDesign.ttf'. The parent directory may not exist, or the user does not have permission to create this file.

按以下优先级依次尝试，多数场景前两步即可解决问题：

• 清理项目构建缓存：在项目根目录打开终端，依次执行以下命令重置构建状态、重新拉取依赖，执行完成后重试构建即可。

  flutter clean
  flutter pub get
  

• 修复路径兼容问题：你的项目存放路径F:\Mobile app\user app\booking_system_flutter中包含空格，Windows环境下部分Gradle构建脚本对带空格的路径存在解析bug，直接将整个项目移动到无空格、无中文/特殊字符的短路径下（例如F:\dev\booking_system_flutter），重新拉取依赖后再执行构建。
• 排查权限与拦截问题：右键项目内的build文件夹，打开「属性-安全」面板，确认当前Windows登录账号对该目录拥有读写、修改的完全控制权限，权限不足时手动为当前账号开放对应权限；如果开启了杀毒软件的文件实时防护功能，临时关闭防护后重试，避免安全软件拦截构建过程的文件写入操作。
• 解除系统长路径限制：如果移动到短路径后仍存在同类报错，按下Win+R输入gpedit.msc打开本地组策略编辑器，依次进入「计算机配置 > 管理模板 > 系统 > 文件系统」，将「启用Win32长路径」选项设置为已启用，重启电脑后再尝试构建。
• 排查依赖兼容性：若以上操作均无效，检查pubspec.yaml中flutter_vector_icons依赖的版本，若版本与当前安装的Flutter SDK不兼容，切换到适配的稳定版本，重新拉取依赖后再构建。
