【问题描述】:
我有一个简单的 python 守护程序,它在执行我的主要测试时在后台运行。这段代码在我的 Ubuntu 机器上运行良好,但自从在我的 Mac 上尝试后,我无法让它工作。
#! /usr/bin/env python
import daemon
import time as t
import subprocess
def logging():
while True:
n = str(10)
m = str(1)
i = t.time()
cpu = open("filepath/to/file" + str(i) + ".txt", "w")
ram = open("filepath/to/file" + str(i) + ".txt", "w")
disk = open("filepath/to/file", "a")
subprocess.call(['adb', 'shell', 'top', '-m', n, '-n', m], stdout=cpu, stderr=cpu)
subprocess.call(['adb', 'shell', 'cat /proc/meminfo'], stdout=ram)
subprocess.call(['adb', 'shell', 'df', '/data'], stdout=disk)
def run():
with daemon.DaemonContext():
logging()
if __name__ == "__main__":
run()
每当我执行此代码时,stderr 都会给我以下输出:
* daemon not running; starting now at tcp:5037
ADB server didn't ACK
Full server startup log: /var/folders/4_/_dcrxz611mv09n6nd404kj_80000gn/T//adb.501.log

我可以使用 adb 连接到我的设备并运行我的主要测试。这个守护进程似乎只是不想在 Mac 上使用 adb。
- python 版本 - 3.8.3
- adb 版本 - 1.0.41
- SDK 版本 - 30.0.1-6435776
- Mac 操作系统 - 10.15.5
感谢任何帮助!
