Question

我在树莓派上运行了一个python脚本，希望在启动时自动运行。在添加温度传感器之前，我一直在进行此操作，直到现在程序在启动时不会自动运行，但是如果手动运行，它将正常运行，没有错误。

启动时是否对某些导入不了解？

有效方法：

我通过在文件末尾附近添加rc.local来修改python /home/pi/myscript.py &。

其中myscript.py =

#!/usr/bin/python3

import RPi.GPIO as GPIO #for GPIO naming convention
import os #for power circuit
import serial #for reading serial port on USB
import time
import threading 

def power_button():

    GPIO.setmode(GPIO.BCM)#set to GPIO Values
    GPIO.setwarnings(False)
    GPIO.setup(4,GPIO.OUT)#relay coil
    GPIO.setup(22,GPIO.OUT)#power LED
    GPIO.setup(27,GPIO.IN)#power button sense
    GPIO.output(4,GPIO.HIGH)#turn on coil
    GPIO.output(22,GPIO.HIGH)#turn on power LED
    powerButton = GPIO.input(27)

    while powerButton ==1: #check for change, then shutdown
        powerButton = GPIO.input(27)

    #change occured, as program left the while loop, proceed below
    GPIO.output(22,GPIO.LOW)#turn off power LED
    os.system('sudo shutdown -h now')


#power button thread
thread1 = threading.Thread(target=power_button) 
thread1.start()

就像上面提到的那样，此代码可以正常运行，并在启动时自动正常运行。

什么不起作用：添加温度传感器导入后，它将不再自动启动，但是如果在pi启动后手动运行，它将运行正常。

myscripy.py，其中添加了更多导入：

#!/usr/bin/python3

import RPi.GPIO as GPIO #for GPIO naming convention
import os #for power circuit
import serial #for reading serial port on USB
import time
import threading 
import adafruit_sht31d #sht temphumid sensor
import board #sht temphumid sensor
import busio #sht temphumid sensor
import adafruit_sht31d #sht temphumid sensor
import requests #for posting



# Create library object using our Bus I2C port for SHT31 temp humid sensor
i2c = busio.I2C(board.SCL, board.SDA)
sensor = adafruit_sht31d.SHT31D(i2c)


def power_button():

    GPIO.setmode(GPIO.BCM)#set to GPIO Values
    GPIO.setwarnings(False)
    GPIO.setup(4,GPIO.OUT)#relay coil
    GPIO.setup(22,GPIO.OUT)#power LED
    GPIO.setup(27,GPIO.IN)#power button sense
    GPIO.output(4,GPIO.HIGH)#turn on coil
    GPIO.output(22,GPIO.HIGH)#turn on power LED
    powerButton = GPIO.input(27)

    while powerButton ==1: #check for change, then shutdown
        powerButton = GPIO.input(27)

    #change occured, as program left the while loop, proceed below
    GPIO.output(22,GPIO.LOW)#turn off power LED
    os.system('sudo shutdown -h now')



#power button thread
thread1 = threading.Thread(target=power_button) 
thread1.start()

有什么想法吗？
