python - ラズベリーパイを使用してPythonでキープレスを検出する方法

Question

キーボードモジュールを使用していますが、このエラーが発生します。

私は他の投稿を見て、彼らが言うように実行し、sudo pip3 install キーボードを使用しましたが、それでも機能しません。

import keyboard
loop = ""


while loop == "":

    if keyboard.read_key() == "w":
        print("You pressed w")



    if keyboard.read_key() == "a":


        print("You pressed a")

    if keyboard.read_key() == "s":
        print("You pressed s")



    if keyboard.read_key() == "d":
        print("You pressed d")

コードを実行すると、そのエラーが発生します。ルートにインストールしたと思いました。
