来自终端的 运行 时 Omxplayer-wrapper 问题
Omxplayer-wrapper problems when run from terminal
我在 Raspberry Pi 上开发了以下程序（我没有创建所有程序，所以其中一些很奇怪）。它基本上应该打开一个带有按钮的 tkinter window，如果你按正确的顺序点击按钮，一个新的过程就会开始。如果按错误的顺序单击按钮，它将播放视频。 所有这些都在 Thonny IDE. 中有效（实际上，除了使用 omxplayer-wrapper 播放视频这一事实之外，程序的细节并不重要）

我的问题是我想在 Pi 启动时 运行，这涉及从终端启动程序。如果我使用 "sudo python3 [file path]"，它会告诉我：“Traceback（最后一次调用）：

我不知道为什么使用 sudo 和不使用 sudo 之间甚至有区别。几个小时以来，我一直在努力解决这个问题，但我不知道。我很抱歉这个节目。
原来我在设置路径的时候需要设置完整路径，而不仅仅是文件名。所以路径更改为 /home/pi/Documents/filename。
