psutil.AccessDenied: psutil.AccessDenied (pid=7868)

Question

我试图用zoom.exe( psutil )杀死一个进程。但是，我得到了一个错误psutil.AccessDenied。我有所有的权限去做这件事，并且已经在另一台pc上进行了测试。

码

def kill_process(PROCNAME):
  for proc in psutil.process_iter():
    if proc.name() == PROCNAME:
      proc.kill()
      print(f'{PROCNAME} was succesfully killed')
  time.sleep(3)

解决了此代码的问题：

def kill_process(PROCNAME):
  for proc in psutil.process_iter():
    try:
      if proc.name().lower() == PROCNAME.lower():
        proc.kill()
        return True
    except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess):
      return False
