安装Python时，使用pypy easy_install

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...

Answer 1

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

Answer 2

You need to install easy_install for pypy manually.

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

Answer 3

At least this worked for me:

$ brew install pypy
$ pypy -m easy_install ipython

$ /usr/local/share/pypy/ipython
