跟着老师的视频一步步敲得，但是一运行就报错，好像是缺少什么文件，求助帮忙看一下怎么才能正常运行。
代码：
import os
import shlex
import signal
import subprocess
from time import sleep
def test_vedio():
cmd=shlex.split("scrcpy --record tmp.mp4")
p = subprocess.Popen(cmd,shell=False,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
print(p)
sleep(10)
os.kill(p.pid,signal.CTRL_C_EVENT)
报错信息：
ERROR [100%]

def record():
cmd = shlex.split(“scrcpy --record tmp.mp4”)
> p = subprocess.Popen(cmd, shell=False, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
