IOError: [Errno 1] Operation not permitted: '/dev/uinput' - macos

Question

I seem to have some problems let python read key event, I wrote this piece of code
for recording while i have space down and stop when i've release it..
import pyaudio
import wave
import keyboard
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=CHUNK)
print("* recording")
frames = []
while keyboard.is_pressed('space'):
data = stream.read(CHUNK)
frames.append(data)
print("* done recording")
stream.stop_stream()
stream.close()
p.terminate()
wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()
But when running this code, I get this error message.
python sound_record.py
* recording
Traceback (most recent call last):
File "sound_record.py", line 24, in <module>
while keyboard.is_pressed('space'):

raise ImportError('You must be root to use this library on linux.')
ImportError: You must be root to use this library on linux.
And when i do it using sudo:
sudo !!
sudo python sound_record.py

uinput = open("/dev/uinput", 'wb')
IOError: [Errno 1] Operation not permitted: '/dev/uinput'
So why am I getting this error message?

Answer 1

You appear to be using the Python package keyboard, whose description is:
Hook and simulate keyboard events on Windows and Linux
If you want to do work with keyboard events on MacOS, you'll need to find a package that does that.
