无法解析pi的主机名

Question

我正在关注makezine教程Raspberry Pi GPIO Pins and Python 我进入“使用RPI.GPIO LIBRARY”这一部分，但下一个命令sudo puthon将无效。我得到unable to resolve host。

我对pi和一般Linux都很新。我也很擅长使用控制台。非常感谢帮助。感谢

整个错误消息是：

sudo: unable to resolve host raspberrypi

Answer 1

1. 打开控制台
2. 输入：cd /home/pi
3. 然后输入：sudo nano myInputSketch.py​​

4. 复制以下代码：

   import RPi.GPIO as GPIO
   GPIO.setmode(GPIO.BCM)
   GPIO.setup(23, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
   GPIO.setup(24, GPIO.IN, pull_up_down = GPIO.PUD_UP)
   
   print("Welcome! Press any button on your bread board. To quit this, press Ctrl + C")
   
   try:
       while True:
           GPIO.wait_for_edge(23, GPIO.RISING)
           print("Button 1 Pressed")
           GPIO.wait_for_edge(23, GPIO.FALLING)
           print("Button 1 Released")
           GPIO.wait_for_edge(24, GPIO.FALLING)
           print("Button 2 Pressed")
           GPIO.wait_for_edge(24, GPIO.RISING)
           print("Button 2 Released")
   except:
       print("Bye bye!")
       GPIO.cleanup()
   

5. 按 Crtl + X 然后 Y 然后按ENTER
6. 输入：sudo python myInputSketch.py​​
7. 享受！
