PyPy is an alternative python interpreter which focuses on speed and memory. PyPy uses JIT compiler. PyPy is a replacement for CPython. It is built using the RPython language that was co-developed with it. The main reason to use it instead of CPython is speed.
Now you can uncompress them either somewhere in your home directory or, say, in /opt, and if you want, put a symlink from somewhere like /usr/local/bin/pypy to /path/to/pypy-5.1.1/bin/pypy. Do not move or copy the executable pypy outside the tree – put a symlink to it, otherwise it will not find its libraries.
ArchLinux:
pacman -Sy pypy # for python2 pacman -Sy pypy3 # for python3
Let's Create and run pypy_django app:
1. Create pypy virtualenv:
Run the following command to create pypy based virtualenv:
virtualenv -p /usr/local/bin/pypy env # if you used different path for pypy installation change the path as required
2. Install django:
First activate the env and then run the follwing command to install django
pip install django
3. Create a django project and run using pypy interpreter.
To create a django project run the cmd:
django-admin startproject pypy_django
To run the django project with pypy simply do
./manage.py runserver
Since our virtualenv links to pypy interpreter, the project now runs with pypy virtualenv
Now you can see a welcome page of Django at http://localhost:8000/
