Raspberry pi script AttributeError: module 'datetime' has no attribute 'now'
Raspberry pi script AttributeError: module 'datetime' has no attribute 'now'
我在尝试 运行 我的 pi 上的脚本时遇到此错误。我尝试导入日期时间,但也出现了错误。我是否缺少缩进或其他功能?

请提供解决此问题的任何帮助。我正在尝试跟随一个门铃,当它通过家庭助理收到 rf 代码 运行ning 时,门铃就会工作。我可以手动 运行 来自 HA 的脚本,当我 运行 上面的脚本出错时。
我已经尝试解决这个问题一个星期了,但我无法解决。我的编码不是很好,但我可以做基本的 python.
谢谢。
datetime
module has a class datetime
有你要的功能
所以使用:
datetime.datetime.now()
而不是 datetime.now()
.
如果您希望保持原样,请将导入语句从 import datetime
更改为 from datetime import datetime
。
To read more about the import system, the docs are your friend.
尝试改变这个:
def post_image():
print('Taking photo')
camera.capture('image.jpg')
file_name = 'image_' + str(datetime.now()) + '.jpg'
camera.capture(file_name) # time-stamped image
with open('image.jpg', "rb") as imageFile:
myFile = imageFile.read()
data = bytearray(myFile)
client.publish('dev/camera', data, mqttQos, mqttRetained) #
client.publish('dev/test', 'Capture!') # to trigger an automation later
print(file_name + 'image published')
进入这个:
def post_image():
print('Taking photo')
camera.capture('image.jpg')
file_name = 'image_' + str(datetime.datetime.now()) + '.jpg'
camera.capture(file_name) # time-stamped image
with open('image.jpg', "rb") as imageFile:
