RPi B3驱动Devastator坦克遇setupterm找不到键盘错误求助

我使用树莓派B3、PiHut MotorShield电机驱动板和迷你WiFi键盘远程控制Devastator坦克，运行控制代码时遭遇setupterm cannot find keyboard错误。此前曾成功用curses库搭配该迷你键盘实现控制，附上代码请求解决。

控制代码 #

import curses  
import PiMotor 
import time
import curses
import os  # added so we can shutdown OK

#Name of Individual MOTORS
m1 = PiMotor.Motor("MOTOR1",1)
m2 = PiMotor.Motor("MOTOR2",1)

#To drive all motors together
motorAll = PiMotor.LinkedMotors(m1,m2)

#Names for Individual Arrows
ab = PiMotor.Arrow(1)
al = PiMotor.Arrow(2)
af = PiMotor.Arrow(3) 
ar = PiMotor.Arrow(4)

# Get the curses window, turn off echoing of keyboard to screen, turn off     
# instant (no waiting) key response, and use special values for curser keys
screen = curses.initscr()
curses.noecho()
curses.cbreak()
screen.keypad(True)

##This segment drives the motors in the direction listed below:
## forward and reverse takes speed in percentage(0-100)

try:
    while True:
        char = screen.getch()
        if char == ord('q'):
            break
        if char == ord('S'):  # Added for shutdown on capital S
            os.system ('sudo shutdown now')   # shutdown right now!
        elif char == curses.KEY_UP:
            af.on()
            motorAll.forward(100) 
        elif char == curses.KEY_DOWN:
            af.off()
            ab.on()
            motorAll.reverse(100) 
        elif char == curses.KEY_RIGHT:
            ar.on()
            ab.off()
            m1.reverse(100)
            m2.forward(100)
        elif char == curses.KEY_LEFT:
            ar.off()
            al.on()
            m1.forward(100)
            m2.reverse(100)
        elif char == 10:
            motorALL.stop()

except KeyboardInterupt:
    #Close down curses properly, inc turn echo back on!
    curses.nobreak(); screen.keypad(0); curses.echo(0)
    curses.endwin()

• 修正终端环境配置：远程运行代码时，必须确保终端为交互式tty环境。执行echo $TERM检查终端类型，若输出为空或无效值，手动设置：export TERM=xterm后再运行代码。避免使用后台运行（如nohup）或非交互式SSH连接，这类场景下curses无法识别键盘。
• 修复代码拼写错误：
  1. except KeyboardInterupt:拼写错误，改为except KeyboardInterrupt:
  2. motorALL.stop()中的变量名错误，改为motorAll.stop()（与前面定义的变量名一致）
• 手动指定终端类型：在curses.initscr()前添加以下代码，强制设置终端环境，避免系统无法找到终端配置：

  os.environ.setdefault('TERM', 'xterm')
  

• 验证键盘输入映射：在终端中先测试迷你WiFi键盘的按键输入，确认方向键、字母键能被正确识别。若远程连接时按键映射异常，可尝试更换SSH客户端，或调整远程桌面的键盘输入设置。
