在没有控制台的情况下使用Popen在pythonw中运行进程 [英] Running a process in pythonw with Popen without a console

问题描述

我有一个程序有一个GUI通过Popen调用运行外部程序：

I have a program with a GUI that runs an external program through a Popen call:

p = subprocess.Popen("<commands>" , stdout=subprocess.PIPE , stderr=subprocess.PIPE , cwd=os.getcwd())
p.communicate()

但是一个控制台弹出，不管我做什么（我也试过传递它的NUL文件句柄）。

But a console pops up, regardless of what I do (I've also tried passing it NUL for the file handle). Is there any way to do that without getting the binary I call to free its console?

推荐答案

从此处：

import subprocess

def launchWithoutConsole(command, args):
    """Launches 'command' windowless and waits until finished"""
    startupinfo = subprocess.STARTUPINFO()
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    return subprocess.Popen([command] + args, startupinfo=startupinfo).wait()

if __name__ == "__main__":
    # test with "pythonw.exe"
    launchWithoutConsole("d:\\bin\\gzip.exe", ["-d", "myfile.gz"])
