我正在尝试在python 3中使用键盘库,但继续导致导入错误.我在Thonny的Windows中运行程序,它工作正常,但我不能在pi中运行它.我尝试以root身份和sudo命令运行它,结果相同.下面是代码和错误.

import keyboard
import time

x=0

while True:
    print (x)
    x=x+1
    print ("Press t to end program")
    if keyboard.is_pressed('t'):
        break
    else:
        pass

print("I'm done")

产量
