问题
I am setting up a virtualenv on a new server, and when I used pip on our requirements file, it kept dying on Twisted. I commented the Twisted line out, and everything else installed fine. At the command line, this is the output I see when I try to install Twisted (the same error I see when I run the entire requirements file once it gets to the Twisted line):
(foo)company@server:~$ pip install twisted
Collecting twisted
Could not find a version that satisfies the requirement twisted (from versions: )
No matching distribution found for twisted
I can install Twisted fine from my dev machine and other servers, and on this server I seem to be able to install other packages fine.
Case and version do not matter. Same result if I use "twisted", "Twisted", "Twisted==15.2.1".
This is an EC2 instance running Ubuntu 14.04.02.

Ok after struggling with this for several hours, I figured out the problem.
Running pip install --verbose twisted helped with the diagnosis.
The error message is misleading. The problem is that I built a custom installation of Python 2.7.10 without having previously installed libbz2-dev. So the steps to fix this were:
sudo apt-get install libbz2-devcd /<untarred python source dir>./configure --prefix=<my install path> --enable-ipv6makemake install
With this done, I can now create virtual environments and pip install Twisted.

I run into this issue when I tried install requirements on python 2.7.16. I've chosen to install package directly from zip archive Twisted releasespip install https://github.com/twisted/twisted/archive/twisted-18.7.0.zip - it works for me
