Python 子进程 Popen 与 Pyinstaller
问题描述
我使用 ffmpeg 来转换一些视频.我用 subprocess.Popen(...) 调用命令
I use ffmpeg for converting some videos. I am calling command with subprocess.Popen(...)
si = subprocess.STARTUPINFO()
si.dwFlags |= subprocess.STARTF_USESHOWWINDOW
self.my_pro = subprocess.Popen(cmd,
stdin=subprocess.PIPE,
stderr=subprocess.PIPE,
startupinfo=si)
(output, error) = self.my_pro.communicate()
我用这个方法杀人
self.my_pro.kill()
不用编译成exe也没关系.
It's okey without compile to exe.
但我使用 pyinstaller 编译，而 --noconsole 子进程不起作用.我必须将 subprocess.Popen(...) 更改为 subprocess.check_output(...)
But i compiled with pyinstaller with --noconsole subprocess not working.
I must change subprocess.Popen(...) to subprocess.check_output(...)
但是这次我不能用 self.my_pro.kill() 杀死进程，这不起作用.
But this time i can't kill process with self.my_pro.kill() this not working.
如何使用 i can kill 运行进程并运行 pyinstaller noconsole?
How i can run process with i can kill and it will run pyinstaller noconsole?
解决方案
正如@jfs 所写，使用 Popen 您必须重定向所有内容.你忘记了 stdout
As @jfs wrote, with Popen you have to redirect everything. You forgot stdout
所以这段代码对我来说不再崩溃了:
So this code doesn't crash for me anymore:
si = subprocess.STARTUPINFO()
si.dwFlags |= subprocess.STARTF_USESHOWWINDOW
self.my_pro = subprocess.Popen(cmd,
stdin=subprocess.PIPE,
stderr=subprocess.PIPE,
stdout=subprocess.PIPE,
startupinfo=si)
