Advanced Python Programming

Setting up PyPy

PyPy is distributed as a precompiled binary that can be downloaded from http://pypy.org/download.html, and it currently supports Python versions 2.7 (beta support in PyPy 5.6) and 3.3 (alpha support in PyPy 5.5). In this chapter, we will demonstrate the usage of the 2.7 version.

Once PyPy is downloaded and unpacked, you can locate the interpreter in the bin/pypy directory relative to the unpacked archive. You can initialize a new virtual environment where we can install additional packages using the following command:

$ /path/to/bin/pypy -m ensurepip$ /path/to/bin/pypy -m pip install virtualenv$ /path/to/bin/virtualenv my-pypy-env

To activate the environment, we will use the following command:

$ source my-pypy-env/bin/activate ...
