nodeenv is not allowed to download iojs

[csillag]

Hi,

When I try to install iojs vie nodeenv, I get this stack trace:

 * Install iojs (1.8.1Traceback (most recent call last):

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

Analyzing the network traffic, I see that we are trying to do an HTTP request for http://iojs.org/dist/v1.8.1/iojs-v1.8.1-linux-x64.tar.gz, and we get a 403.

Looking at the body of the 403 message, I can extract this information:

• Access denied | iojs.org used CloudFlare to restrict access
• The owner of this website (iojs.org) has banned your access based on your browser's signature (21d0f4c3229b0aa2-ua48).

The way I interpret this, it looks like (until the iojs.org guys change their settings) it will be impossible to install iojs using nodeenv. (Or whichever library, that was responsible for generating this "browser signature".)

However, downloading iojs with (for example) wget works just fine....

Do you have any idea where this "browser signature" thing comes from? Or why the iojs guys decided to forbid downloads from nodeenv?

Thank you for the help!

This is going to become a bigger problem because nodejs.org is shifting to CloudFlare too. Can I suggest changing the urlopen() used to fetch the source to include a custom User-Agent for the tool, something like:

import urllib
...
req = urllib.request.Request(
    node_url, 
    data=None, 
    headers={
        'User-Agent': 'Nodeenv'
    }
)
f = urllib.request.urlopen(req)

Or even pretend to be a normal browser with a standard User-Agent.

It works for me, too. Problem solved, as far as I am concerned.

Shall I close this issue now?
