子进程 Popen 找不到 'play'

Question

子进程的 Popen 找不到 'play' 或 'aplay'。

我的 OS 是 Mac10.13.6，当我从 subprocess.py 调用 Popen 并执行流动代码时

import platform
from subprocess import Popen

player = 'play' if platform.system() == 'Darwin' else 'aplay'
Popen([player, '-q', filename])

我收到以下错误

  File "/Users/lyuzhiliang/mycroft-precise/precise/util.py", line 78, in play_audio
    Popen([player, '-q', filename])
  File "/Users/lyuzhiliang/anaconda3/lib/python3.6/subprocess.py", line 709, in __init__
    restore_signals, start_new_session)
  File "/Users/lyuzhiliang/anaconda3/lib/python3.6/subprocess.py", line 1344, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'play': 'play'

我需要安装一些依赖吗？

我不是很确定，我想应该是afplay吧。也许尝试给出完整路径并自己寻找二进制文件。（我觉得/usr/bin/afplay）

子进程 Popen 找不到 'play'

Subprocess Popen couldn't find 'play'

subprocess

popen

python-3.x
