RPi5：gpiozero KeyError 和 SOC 外设基地址错误

Question

我正在尝试打开/关闭 LED 闪烁，以确保我的树莓派 5 正常工作。这是一款全新的 RPi5。我的 GPIO 插脚上有一个 GPIO 扩展板。我的电路很简单，应该不是问题。 LED 连接到 GPIO17 连接。这是我的Python代码

from gpiozero import LED
from time import sleep

led = LED(17)

try:
    while True:
        led.on()
        print('...LED ON')
        sleep(0.5)
        led.off()
        print('LED OFF...')

        sleep(0.5)

except KeyboardInterrupt:
    pass

这是我运行时遇到的错误。

During handling of the above exception, another exception occurred:

我的 python 脚本也拥有完整的权限。我知道这个问题已在不同的网站上多次提到，但我似乎无法在任何地方找到一个好的解决方案。希望看过的人帮忙解答一下！如果有人知道好的解决方案，请链接！

我也有同样的问题。进行最新的更新，它现在就可以工作了。我认为这是gpiochip文件夹命名的问题。祝你好运！
