[英]Python Subprocess Popen with Pyinstaller
I use ffmpeg for converting some videos. 我使用ffmpeg转换一些视频。 I am calling command with subprocess.Popen(...)
我用subprocess.Popen(...)调用命令
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()
and i kill with this method 我用这种方法杀了
self.my_pro.kill()
It's okey without compile to exe. 这是没有编译到exe的okey。
But i compiled with pyinstaller
with --noconsole
subprocess not working. 但我编译与
pyinstaller
与--noconsole
子--noconsole
无法正常工作。 I must change subprocess.Popen(...)
to subprocess.check_output(...)
我必须将
subprocess.Popen(...)
更改为subprocess.check_output(...)
But this time i can't kill process with self.my_pro.kill()
this not working. 但是这次我不能用
self.my_pro.kill()
来杀死进程。
How i can run process with i can kill and it will run pyinstaller noconsole? 我怎么可以运行进程,我可以杀死它将运行pyinstaller noconsole?
As @jfs wrote, with Popen
you have to redirect everything. 作为@jfs写道,与
Popen
你要重定向一切。 You forgot stdout
你忘记了
stdout
So this code doesn't crash for me anymore: 所以这段代码不再对我崩溃:
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)
