没有名为“picamera”的模块

我关注了这个网站 （https://www.pyimagesearch.com/2015/03/30/accessing-the-raspberry-pi-camera-with-opencv-and-python/ https://www.pyimagesearch.com/2015/03/30/accessing-the-raspberry-pi-camera-with-opencv-and-python/）来设置我的 picamera，但我的 picamera 模块有问题。我确实安装了picamera模块，这张图片来自pip freeze。

您可以看到我已经有了 picamera 1.13，但是当我尝试 test_image.py 时，它显示“没有名为‘picamera’的模块”。

我已经卸载并安装了很多次，但错误仍然存​​在。我该如何解决？

test_image.py

# import the necessary packages
from picamera.array import PiRGBArray
from picamera import PiCamera
import time
import cv2

# initialize the camera and grab a reference to the raw camera capture
camera = PiCamera()
rawCapture = PiRGBArray(camera)

# allow the camera to warmup
time.sleep(0.1)

# grab an image from the camera
camera.capture(rawCapture, format="bgr")
image = rawCapture.array

# display the image on screen and wait for a keypress
cv2.imshow("Image", image)
cv2.waitKey(0)

对于 python3，您必须尝试下面的命令。请记住，您需要在主目录中打开终端。

sudo -H apt install python3-picamera
sudo -H pip3 install --upgrade picamera[array]

让我知道它是否有效！
