Hello

I have spotted issue while installed nodeenv on my computer. I'm getting error while installation when python is trying to connect to "https://nodejs.org/dist/latest/":

Traceback (most recent call last):
  File "/home/dariusz/.virtualenvs/wallpaper/bin/nodeenv", line 9, in <module>
    load_entry_point('nodeenv==0.13.3', 'console_scripts', 'nodeenv')()

    opt.node = get_last_stable_node_version()
  File "/home/dariusz/.virtualenvs/wallpaper/src/nodeenv/nodeenv.py", line 813, in get_last_stable_node_version
    response = urlopen('https://%s/dist/latest/' % (src_domain))

    return opener.open(url, data, timeout)
  File "/usr/lib/python2.7/urllib2.py", line 437, in open
    response = meth(req, response)

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 403: Forbidden

I connect by curl using HEAD from python "curl -H "User-agent: Python-urllib/2" "https://nodejs.org/dist/latest/"" and this is what i got:

@ekalinin http://stackoverflow.com/questions/802134/changing-user-agent-on-urllib2-urlopen

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('User-Agent', 'nodeenv/1.0 (https://github.com/ekalinin/nodeenv)')
r = urllib2.urlopen(req)
