使用Python库Winotify创建通知时遇FileNotFoundError错误求助

问题重现 #

使用Winotify库创建Windows Toast通知时，执行测试脚本后触发FileNotFoundError。测试脚本如下：

from winotify import Notification

toast = Notification(app_id="windows app",
                     title="Winotify Test Toast",
                     msg="New Notification!")

toast.show()

错误信息 #

运行脚本后抛出以下错误：

                       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [WinError 2]  The system cannot find the file specified 

排查与解决 #

已尝试以下操作但未解决问题：

• 卸载并重新安装Winotify库
• 切换至Python 3.9版本

最终定位问题根源：PowerShell未添加至系统PATH环境变量中。将PowerShell的路径（通常为C:\Windows\System32\WindowsPowerShell\v1.0）添加到系统PATH后，重新运行脚本即可正常显示Toast通知。
