Bottle: BrokenPipeError: [Errno 32] Broken pipe

Bottle: BrokenPipeError: [Errno 32] Broken pipe

我写了一些 Python 应该通过使用 LED-Strip 做一些事情来对一些 webhook 做出反应。我在 Raspberry Pi 运行 Raspbian 上 运行 使用启动时启动的 Xterm window。 该程序启动并运行了几分钟,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,有时它什么都不做。我试过 运行 分别发送到 LED 灯带,效果很好。我也尝试过使用不同的 Bottle 服务器,但也无济于事。

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')

经过大量调试解决,显然 Magichue 库忘记了我的初始声明:

light = magichue.Light('192.168.1.36')

一段时间后。
