私が取り組んでいる次のプログラムがあります (すべてを作成したわけではないため、一部はかなり奇妙です) Raspberry Pi で。基本的には、ボタン付きの tkinter ウィンドウを開くことになっています。ボタンを正しい順序でクリックすると、新しいプロセスが開始されます。ボタンが間違った順序でクリックされると、ビデオが再生されます。これらはすべて Thonny IDE で機能します。(実際、プログラムの詳細は、ビデオの再生に omxplayer-wrapper を使用しているという事実以外はあまり重要ではありません)

私の問題は、Piの起動時にこれを実行したいということです。これには、端末からプログラムを起動することが含まれます。「sudo python3 [file path]」を使用すると、「Traceback (most recent call last): File "/home/pi/Documents/alienPasscodeV2.py", line 10, in from omxplayer.player import OMXPlayer ImportError」と表示されます: 「omxplayer」という名前のモジュールはありません。
「python3 [ファイルパス]」だけを使用すると、ビデオを再生する必要があるまで動作し始めます。それからそれは私に言います：
「Tkinter コールバック トレースバックの例外 (最新の呼び出しが最後):

sudo を使用する場合と使用しない場合に違いがある理由さえわかりません。私はこれを何時間も理解しようとしてきましたが、わかりません。こんな番組ですみません。
