在树莓派上安装MFRC522模块时出错

Question

我刚购买了RFID阅读器，但MFRC522 python模块遇到了问题。例如，当我运行Read.py文件时，它显示该错误：

Traceback (most recent call last):
File "..."
import SimpleMFRC522
File "..."
import MFRC522
File "..."
import spi

Read.py代码为：

#!/usr/bin/env python

import RPi.GPIO as GPIO
import SimpleMFRC522

reader = SimpleMFRC522.SimpleMFRC522()

try:
        id, text = reader.read()
        print(id)
        print(text)
finally:
        GPIO.cleanup()
