easy_install with pypy while Python is installed

Question

I installed PyPy while still having Python 2.7 on my system.

How do I install and then use easy_install with PyPy?
What is the syntax for distinguishing where I want to install to with easy_install?
Should I set any environment variables for ease of use?

I'm on Windows, but these questions seem relevant for all platform...

An alternative solution is to install pip. Following the instructions in pip's documentation:

wget https://bootstrap.pypa.io/get-pip.py
pypy get-pip.py
pypy -m pip install ipython

Prefixing with `sudo` is generally needed. – Eric O. Lebigot May 12 '15 at 05:53
@EOL: running pip as root is not recommended. Running with `--user` or in a virtualenv is a much less horrible idea. – Wooble Jan 20 '16 at 15:53
This is true unless you want to install Python packages for all users, right? or is there officially a better method (beyond using a general package manager when possible)? – Eric O. Lebigot Jan 20 '16 at 20:34

You need to install easy_install for pypy manually.

It's explained in the answer to this question : Installing Python eggs under PyPy

If you have python's executable in your path, use `pypy [whatever]` syntax for all installations so that it will install under pypy and not python – Jonathan Livni Dec 28 '11 at 15:23

At least this worked for me:

$ brew install pypy
$ pypy -m easy_install ipython

$ /usr/local/share/pypy/ipython
Python 2.7.3 (480845e6b1dd, Jul 31 2013, 10:58:28)
Type "copyright", "credits" or "license" for more information.

IPython 1.1.0 -- An enhanced Interactive Python.

object?   -> Details about 'object', use 'object??' for extra details.

This may work, but I haven’t seen any recommendations for using `easy_install` that weren’t written several years ago. For the past ≈2 years, `setuptools` has been the unifying standard. (Before that was a competition between `setuptools` and `distribute`; they eventually merged into the current `setuptools`.) I’m less familiar with pypy (and whether it needs something Pythons 2 & 3 don’t), but it’s worth double-checking this, just in case. – Zearin May 04 '15 at 12:29
