瓶子:BrokenPipeError:[Errno 32] 断管 [英] Bottle: BrokenPipeError: [Errno 32] Broken pipe
问题描述
我写了一个小 Python,它应该通过用 LED-Strip 做一些事情来对一些 webhooks 做出反应.我正在使用在启动时启动的 Xterm 窗口在运行 Raspbian 的 Raspberry Pi 上运行它.程序启动并正常运行几分钟,但随后停止工作.我做了一些调试,发现有时程序会在一个 CPU 核心上使用 100%,有时它会吐出BrokenPipeError: [Errno 32] Broken pipe"错误,有时它什么也不做.我试过单独运行发送到 LED 灯条,效果很好.我也尝试过使用不同的 Bottle 服务器,但也无济于事.
I've written a little Python that is supposed to react to some webhooks by doing some stuff with a LED-Strip. I'm running this on a Raspberry Pi running Raspbian using a Xterm window that starts at startup. the program starts and runs fine for a few minutes but then it stops working. I've done some debugging and found that sometimes the program would use 100% on one CPU core, sometimes it spits out the 'BrokenPipeError: [Errno 32] Broken pipe' error and sometimes it just doesn't do anything. I've tried running the sending to LED-strip separately and that worked fine. I've also tried using different Bottle servers but also to no avail.
这是我发现的回溯:

这是整个程序:
import time
import datetime
import magichue
from bottle import route, run
light = magichue.Light('192.168.1.36')
def flash(r, g, b):
light.mode = magichue.NORMAL
light.rgb = (0, 0, 0)
time.sleep(0.5)
light.rgb = (r, g, b)
time.sleep(0.4)
light.rgb = (0, 0, 0)
time.sleep(0.5)
light.rgb = (r, g, b)
time.sleep(0.4)
def fadein(r, g, b, tr=1):
light.mode = magichue.NORMAL
while tr <= 25:
r = r + 10
g = g + 10
b = b + 10
light.rgb = (r, g, b)
time.sleep(0.5)
tr = tr + 1
else:
light.rgb = (255, 255, 255)
@route('/flashgreen')
def index():
print("Im here")
x = datetime.datetime.now()
if 10 <= x.hour <= 22:
time.sleep(0.1)
light.update_status()
if light.on:
pr = light.rgb
flash(0, 255, 0)
light.rgb = pr
else:
flash(0, 255, 0)
light.on = False
@route('/fadein')
def index():
print("Im here")
fadein(0, 0, 0)
@route('/setcolor/<r>/<g>/<b>')
def index(r, g, b):
print("Im here")
light.mode = magichue.NORMAL
light.rgb = (int(r), int(g), int(b))
run(host='0.0.0.0', port=4783, server='paste')
推荐答案
经过大量调试解决,显然是 Magichue 库忘记了我最初的声明:
Solved after a lot of debugging, apparently the Magichue library forgets my initial declaration of:
light = magichue.Light('192.168.1.36')
一段时间后.
