Occurrence event

[Stada] Script that will call you when Pokemon GO is released When I tried to plagiarize the above article and execute the script with cron The following error occurs when executing a command in the subprocess module of python

python poke_check.py 
Traceback (most recent call last):
  File "poke_check.py", line 47, in <module>
    start()
  File "poke_check.py", line 43, in start
    subprocess.call("echo 'not open'")
  File "/usr/lib/python2.7/subprocess.py", line 522, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1335, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Cause / Solution

http://stackoverflow.com/questions/18962785/oserror-errno-2-no-such-file-or-directory-while-using-python-subprocess-in-dj

Solved by the stackoverflow article above.

It seems that a flag is required when passing the command to be executed as a character string.

subprocess.call("(Command you want to execute)", shell=True)
