title: Python 3.6 with windows and nmap
body: <p>Is it possible that Nmap doesn't work on windows with python 3.6?
  Nmap folders are installed but I still get an error message. 
  I tried in console <code>python -m pip install nmap</code> and also
  <code>python -m pip install python-nmap</code>.</p>
  
  <p>I tried this script from an earlier post:</p>
  
  <pre><code>import nmap
  nm = nmap.PortScanner()
  
  for host in nm.all_hosts():
      print(host)
      print(nm[host].get('osclass', 'unknown'))
  </code></pre>
  
  <p>Here is the error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "C:\Users\bart\Desktop\vortex\nmap script 1.py", line 2, in &lt;module&gt;
      nm = nmap.PortScanner()
    File "C:\Users\bart\AppData\Local\Programs\Python\Python36\lib\site-packages\nmap\nmap.py", line 131, in __init__
      os.getenv('PATH')
  nmap.nmap.PortScannerError: 'nmap program was not found in path. PATH is :
