Gooey Python点击Start报错：路径未指定问题排查求助

我编写了如下Gooey Python代码：

from gooey import Gooey, GooeyParser

@Gooey
def main():
    """Takes 2 number as input and output the sum"""
    parser = GooeyParser()
    parser.add_argument("num_1", help="Enter num1", action= "store")
    parser.add_argument("num_2", help="Enter num2", action= "store")
 
    args = parser.parse_args()

    print(int(args.num_1) + int(args.num_2))

main()

界面可正常打开，但输入num_1和num_2后点击Start执行求和操作失败，提示“path is not specified”，报错栈信息如下：

请问该如何解决以正常显示求和结果？

这个错误根源是Windows环境下Gooey调用subprocess时无法定位Python可执行文件，尤其你使用的是微软商店版本的Python（路径包含WindowsApps），这类版本存在路径调用权限限制。

以下是可行的解决办法：

• 指定Python可执行路径：在@Gooey装饰器中添加python_cmd参数，填入你Python.exe的完整路径。比如：

  @Gooey(python_cmd=r"C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.11_3.11.2032.0_x64__qbz5n2kfra8p0\python.exe")
  

  确保路径与报错信息中的Python路径完全一致，也可以改用独立安装版Python的路径，比如r"C:\Python311\python.exe"。

• 更换为标准独立安装版Python：微软商店版Python存在诸多权限和调用限制，建议卸载后安装官网标准Python包，安装时勾选"Add Python to PATH"选项。这样Gooey能自动识别Python路径，无需额外配置python_cmd。

• 验证修复：修改代码后重新运行，输入数字点击Start，求和结果会正常显示在Gooey的控制台区域。
