This was a tricky one for me. I was trying to use wget to download a file but it wouldn't work properly!
subprocess.call("wget --tries=3 --retry-connrefused http://dl.dropbox.com/u/446679/dog-bites-cat.jpg") Once I ran it...
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/lib/python2.6/subprocess.py", line 470, in call
return Popen(*popenargs, **kwargs).wait()
File "/usr/lib/python2.6/subprocess.py", line 623, in __init__
errread, errwrite)
File "/usr/lib/python2.6/subprocess.py", line 1141, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory
What the hell? Everything is right!
Turns out I was missing a certain keyword in the call. Some functions require you to add in "shell = True".
subprocess.call("wget --tries=3 --retry-connrefused http://dl.dropbox.com/u/446679/dog-bites-cat.jpg", shell = True)
