Downloading and Installing PyPy¶
Using a packaged PyPy¶
Some Linux distributions provide a pypy package. Note that in order to install additional modules that require compilation, you may need to install additional packages such as pypy-dev. This will manifest as an error about “missing Python.h”. Distributions do not as of yet supply many pypy-ready packages, if you require additional modules we recommend creating a virtualenv and using pip.
Download a pre-built PyPy¶
The quickest way to start using PyPy is to download a prebuilt binary for your OS and architecture. You can either use the most recent release or one of our development nightly build. Please note that the nightly builds are not guaranteed to be as stable as official releases, use them at your own risk.
PyPy is ready to be executed as soon as you unpack the tarball or the zip file, with no need to install it in any specific location:
$ tar xf pypy-2.1.tar.bz2 $ ./pypy-2.1/bin/pypy Python 2.7.3 (480845e6b1dd, Jul 31 2013, 11:05:31) [PyPy 2.1.0 with GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. And now for something completely different: ``PyPy is an exciting technology that lets you to write fast, portable, multi-platform interpreters with less effort'' >>>>
If you want to make PyPy available system-wide, you can put a symlink to the
pypy executable in
/usr/local/bin. It is important to put a symlink
and not move the binary there, else PyPy would not be able to find its
Installing more modules¶
If you want to install 3rd party libraries, the most convenient way is to install pip using ensurepip (unless you want to install virtualenv as explained below; then you can directly use pip inside virtualenvs):
$ ./pypy-xxx/bin/pypy -m ensurepip $ ./pypy-xxx/bin/pip install pygments # for example
Third party libraries will be installed in
the scripts in
Installing using virtualenv¶
It is often convenient to run pypy inside a virtualenv. To do this you need a recent version of virtualenv – 1.6.1 or greater. You can then install PyPy both from a precompiled tarball or from a mercurial checkout:
# from a tarball $ virtualenv -p /opt/pypy-xxx/bin/pypy my-pypy-env # from the mercurial checkout $ virtualenv -p /path/to/pypy/pypy/translator/goal/pypy-c my-pypy-env
Note that bin/python is now a symlink to bin/pypy.
