Installing twisted on Windows 10 64 bit under python 2.7

Question

Does anyone know how to do this. I have googled and the best that I could come up with was to do:

pip install autobahn[twisted]

when I do that I get this error in the command window

C:\Users\<User Name>\Desktop>pip install autobahn[twisted]

I have no idea how to fix the error

Voting to close as this isn't a programming question. Instead, it's a question about how to use a package mangement tool, "pip" (and possibly a report of a bug in that software). — Jean-Paul Calderone, Mar 18 '18 at 10:34
Upon actually parsing the traceback, seems like the error occurs when trying to make a request to some url (`self.request('GET', url, **kwargs)`) — notorious.no, Mar 18 '18 at 23:57

Go to University of California Irvine's Unofficial Windows Binary for Python Extension Packages and download the Twisted wheel file. This is the easy way. The hard way requires a compiler (comes packaged in Windows Built Tools) to be installed.

PLEASE NOTE!!!! For anyone stumbling onto this thread, only the latest package is available for download (usually) through the University of California Irvine site, so it would be wise to SAVE the binaries for future use. This is very useful if a specific version is required. Otherwise the specific compiler needs to used to compile packages.

This doesn't really seem like the answer to this question. The question is basically "pip has this error when downloading a package" and the answer is "manually go to this semi-mirror and manually get the package yourself". That may be a useful workaround but it's not an *answer*. What's going on with pip? – Jean-Paul Calderone Mar 18 '18 at 10:33
That's a good point. I basically assumed a bit much and based on what I dealt with in a Windows env, I figured he just needed install twisted by any means. I don't have a Windows machine to test these days :( – notorious.no Mar 18 '18 at 23:41
Yea. It's good _support_ but that's a bit different from "good SO content" I think. – Jean-Paul Calderone Mar 19 '18 at 01:02
Ok I hate to sound dumb. But what do you do after you download the .whl file. I am just gettting back into python programming. I stopped in the mid 2005s. Back then you downloaded a .zip or .arc or MAYBE a .gz. – Shaba1 Mar 19 '18 at 03:15
You should be able to something like this `python -m pip install twisted.whl` or just double click it – notorious.no Mar 19 '18 at 04:15
