Can't use python-nmap, OSError: [Errno] 2

Question

I am using python2 in ubuntu. Just started reading the documentation of nmap. After just using the PortScanner I get an error.

>>> import nmap
>>> nm = nmap.PortScanner()
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    nm = nmap.PortScanner()
  File "usr/local/lib/python2.7/dist-packages/nmap/nmap.py", line 118, in __init__
    p = subprocess.Popen(['nmap', '-V'], bufsize=1000, stdotut=subprocess.PIPE)
  File "usr/lib/python2.7/subprocess,py", line 679, in __init__
    errread, errwrite)
  File "usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Answer 1

It seems you don't have nmap installed in your OS. Try doing: sudo apt-get install nmap and test it later.

Hope this helps!
