It worked for me, on Windows 10, Python 3.4 in a fresh virtualenv:

PS 22:00 (VE-1) {00:00.015} C:\Work\Scratch
->pip install pyreadline
You are using pip version 7.1.0, however version 7.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade
pip' command.

Your failure appears to be Sphinx-related, maybe pyreadline's setup.py
doesn't try to build the docs if Sphinx isn't present?

Yes, I just reinstalled with Sphinx installed, and that triggered the issue.

I'd suggest building a pyreadline wheel in a virtualenv without Sphinx
installed, and use that to install in your target environment.

Then report a bug to the babel project, which is where the error appears to lie:
