树莓派4B摄像头脚本手动正常但开机自启动报错求助

初始错误与解决过程 #

搭建远程摄像头时，运行脚本出现如下错误：

RuntimeError: module compiled against API version 0xf but this version of numpy is 0xd
Traceback (most recent call last):
File "/home/pi/pi-camera-stream-flask/main.py", line 7, in <module>
from camera import VideoCamera
File "/home/pi/pi-camera-stream-flask/camera.py", line 5, in <module>
import cv2 as cv
File "/usr/local/lib/python3.9/dist-packages/cv2/__init__.py", line 181, in <module>
bootstrap()
File "/usr/local/lib/python3.9/dist-packages/cv2/__init__.py", line 153, in bootstrap
native_module = importlib.import_module("cv2")
File "/usr/lib/python3.9/importlib/__init__.py", line 127, in import_module
return _bootstrap._gcd_import(name[level:], package, level)
ImportError: numpy.core.multiarray failed to import

曾尝试运行以下命令，均提示找不到包：

sudo apt-get install VideoCamera
sudo apt-get install camera

问题解决步骤 #

1. 执行命令升级numpy：

pip install numpy --upgrade

升级后出现新错误：

Traceback (most recent call last):
File "/home/pi/pi-camera-stream-flask/main.py", line 7, in <module>
from camera import VideoCamera
File "/home/pi/pi-camera-stream-flask/camera.py", line 6, in <module>
from imutils.video.pivideostream import PiVideoStream
ModuleNotFoundError: No module named 'imutils'

2. 安装缺失的imutils模块：

pip install imutils

现在手动在Thonny中运行脚本一切正常，可在同一WiFi网络的设备上查看摄像头实时画面。

当前核心问题 #

尝试让脚本在树莓派4B开机时自动运行，已尝试教程内方法及另外两种开机自启动配置方法，但三种方法均触发最初的numpy版本不匹配错误，手动运行则完全正常。
