排查与解决步骤 #

• 确认工作目录：执行briefcase dev前必须进入briefcase new生成的项目根目录（比如默认的HelloWorld文件夹），用cd 项目名称切换后重试。
• 检查配置文件存在性：确认项目根目录下是否有pyproject.toml文件。如果缺失，重新执行briefcase new，确保全程无中断。
• 升级Briefcase版本：当前使用的0.3.16版本较旧，可能存在Python3.8兼容性问题，执行以下命令升级：

  pip install --upgrade briefcase
  

  升级后重新创建项目并测试。
• 更换项目路径：如果项目在Win11受保护路径（如C:\Program Files），移到普通用户目录（如C:\Users\你的用户名\Projects）后重试。
• 重新初始化项目：删除项目目录下的.briefcase文件夹，执行briefcase init重新生成配置，再运行briefcase dev。
