Question

I\'m using the killableprocess package (built on top of subprocess) for running processes Whenever I run the \"killableprocess.Popen(command)\" piece of code in my script I

Answer 1

What I found when running into this with the subprocess module is that the first entry in 'args' (the first parameter to subprocess.Popen()) needed to be just the executable name with no path and I needed to set executable in the argument list to the full path of my executable.

app = 'app.exe'
appPath = os.path.join(BIN_DIR, app)

commandLine = [app, 'arg1', 'arg2']
process = subprocess.Popen(commandLine, executable=appPath)

Answer 2

I solved a similar problem I had by switching to the process directory (I was trying to use inkscape) and it solved my problem

import subprocess
inkscape_dir=r"C:\Program Files (x86)\Inkscape"
assert os.path.isdir(inkscape_dir)
os.chdir(inkscape_dir)
subprocess.Popen(['inkscape.exe',"-f",fname,"-e",fname_png])

Maybe switching to the process directory will work for you too.

Answer 3

Make sure that your paths include the name of the executable file (inkscape.exe)

Answer 4

Do you specify full path to executable you are passing to Popen (the first item in argv)?

Answer 5

Alternatively, if your module doesn't work, you can use the «subprocess» module:

import subprocess, os, time

process = subprocess.Popen("somecommand", shell=True)
n = 0
while True:
    if not process.poll():
        print('The command is running...')
        if n >= 10:
            pid = process.pid()
            os.kill(pid, 9) # 9 = SIGKILL
    else:
        print('The command is not running..')
    n += 1
    time.sleep(1)
