如何创建包含gpiozero的可执行文件？

Question

我为raspberrypi中的GPIO引脚写了一个这样的脚本。

from gpiozero import LED
led = LED(12)

并且运行正常。但当创建可执行文件时使用pyinstaller，并执行文件。我有这个错误：

/tmp/_MEIFanWCr/gpiozero/devices.py:279: PinFactoryFallback: Falling back from rpigpio: No module named 'gpiozero.pins.rpigpio'

如何创建包含gpiozero的可执行文件？

Answer 1

我们必须这样写：

from gpiozero.pins.native import NativeFactory
from gpiozero import LED

factory = NativeFactory()
led = LED(12, pin_factory=factory)
