"WindowsError: [Error 2] The system cannot find the file specified"
I had the same error when I want to envoke a programm which isn't installed (I use ubuntu instead of windows).
http://docs.python.org/2/library/subprocess.html#exceptions
try to excute the command manually in the shell , to get the real error
or use this fine method :
from subprocess import CalledProcessError, check_output try: output = check_output(["ls", "non existent"]) except CalledProcessError as e: print(e.returncode) N.B: in my system (ubuntu) , I get :
ls: cannot access non existent: No such file or directory 2
In windows there is no "ls" command , you will get exception meaning that.
from : Check a command's return code when subprocess raises a CalledProcessError exception
check this : Using subprocess to run Python script on Windows
Use list while running command via subproccess. list should be created by follows: Suppose you want ot run command :
ls -l Then command should be
cmd = ["ls" "-l" ] subprocess.Popen(cmd)
