eGenix PyRun™ is our one-file, no installation version of Python, making the distribution of a Python interpreter to run based scripts and applications to Unix based systems as simple as copying a single file.
Please note that the documentation for this release is not yet as complete and comprehensive as it should be. We're working on it.
● Small footprint: only about 11 MB in size. Can be compressed to just 3-4 MB using gzexe or upx.
● Full Python Support: PyRun works with Python 2.5, 2.6 and 2.7.
● Cross Platform Support: PyRun runs on the following platforms: Linux, FreeBSD and Mac OS X.
● Full 64-bit Support: PyRun can be built on both 32-bit and 64-bit builds on all supported platforms.
● Highly Portable Codebase: in addition to the already supported platforms for PyRun, we provide custom porting services for more exotic platforms.
● Easy Installation: Simply drop the executable into a directory and start using it. No installers, no packagers and only a minimal set of dependencies needs to be provided.
● Fully Relocatable: eGenix PyRun uses relative search paths, so you can easily move the installation around.
● Compatible with setuptools/distribute, easy_install, pip: Great care was taken to make sure that PyRun can be used with setuptools et al.
eGenix PyRun needs these third party tools to be available on the target machines:
● OpenSSL0.9.8/1.0.0 or later
● zlib1.2 or later
● SQLite3.4 or later
● bzip21.0 or later
Future versions of PyRun will add more flexibility to the build process to make the requirements more customizable.
If you want to compile PyRun yourself, you will also need the development packages of the above tools, a C compiler and a GNU make compatible make installed.
Installation of eGenix PyRun can be done in two ways:
● from sources by compiling your own version, or
● downloading and installing a precompiled binary.
The following sections explain both options.
eGenix PyRun currently does not support Windows platforms.
We will look into making eGenix PyRun compatible with Windows in one of the upcoming releases.
To simplify the installation of eGenix PyRun and make it as easy to use as virtualenv, we've created a shell script called install-pyrun that you can download from our server.
After download, all you have to do is make the executable and place it on your path.
With the script, you can automate the whole installation process easily. In order to install the set of eGenix PyRun (together with the Python include files and some extra C extensions from the stdlib that are not compiled into PyRun), distribute and pip to a new directory targetdir, just run the following command:
This will then download a suitable eGenix PyRun binary distribution for your platform, install distribute and pip:
$ install-pyrun targetdir
Installing eGenix PyRun ...
Installing distribute ...
Installing pip ...
eGenix PyRun was installed in targetdir
To run eGenix PyRun, use targetdir/bin/pyrun
$ cd targetdir
$ bin/pyrun -c 'print "Hello World!"'
pyrun 2.7.3 (default, Jun 29 2012, 23:21:21)
[GCC 4.2.1 (SUSE Linux)]
Thank you for using eGenix PyRun. Type "help" or "license" for details.
The script comes with a set of options to customize the version, platform, Unicode variant and also allows disabling installation of distribute and pip as well as permit installation from a local PyRun archive.
Simply run the script with option -h to see all options:
$ install-pyrun -h
Install eGenix PyRun in a given target directory.
install-pyrun [options] targetdir
-m: install eGenix PyRun only (no distribute and pip)
-l: log installation to targetdir/pyrun-installation.log
-q: quiet installation
install PyRun for Python version 2.7 (default), 2.6, 2.5
install PyRun for Python Unicode version ucs2 (default)
install PyRun version 1.0.0 (default)
install PyRun for the given platform; this is usually
use the given PyRun distribution file; this overrides
all other distribution selection parameters
show this text
show the script version
Without options, the script installs eGenix PyRun, distribute and
pip in targetdir.
If you'd rather install eGenix PyRun manually, you can do so by downloading the prebuilt binaries yourself. Please see the next section for details.
Simply download a suitable binary distribution for the version of Python and platform you need and extract it to a base directory where you'd like PyRun to live. Then use the eGenix PyRun executable like you'd use a regular Python interpreter, e.g.
You can also put pyrun into the shebang of the script, e.g.
# Hello World Demo
print "Hello World!"
Please note that the binary distributions contain more than just the PyRun executable. They also come with a few extra standard library extensions which are normally not part of PyRun and the include files needed to compile Python extensions for use with PyRun.
If you are just looking for the plain single-file PyRun executable, only extract the file bin/pyrunX.X (with X.X being the underlying Python version, e.g. 2.7) from the binary distributions.
If you want to install other libraries or packages for use in eGenix PyRun, you need to pay a little more attention to where you copy the executable. eGenix PyRun assumes the following directory layout relative to the executable (with X.X being the underlying Python version, e.g. 2.7):
The lib/pythonX.X directory is used as location of the Python libaries and automatically put on sys.path in case it is available. Optional packages installed through distutils or setuptools will go into the corresponding lib/pythonX.X/site-packages/ directory.
The lib/pythonX.X directory may also contain Python standard library extension modules in the lib-dynload/ sub-directory which are not integrated into the eGenix PyRun executable. The prebuilt binary distributions come with a set of such extensions.
The include/pythonX.Xdirectory is only needed in case you want to compile Python C extensions. It is available as part of the prebuilt binary distributions we make available.
Please note that while eGenix PyRun itself is fully relocatable after installation due to the relative search path, the tools setuptools/distribute and pip are not. They hard-code the paths into their scripts, so you can not relocate an installation with these tools installed to a different parent directory without a reinstallation.
In order to build your own version, simply download the above source archive, untar/unzip it to a temporary directory and follow these steps:
This will download the Python source distribution and start a build of eGenix PyRun. The result will be installed to the directory /usr/local/ using the directory layout as described above.
If you'd like to build a binary distribution archive, use the following commands instead:
You can then pick up the distribution archive from the dist/ directory.
To run some simple tests, please use the test-distribution target:
This will install the distribution you just built, install it locally in a test directory and run a few tests, including pip installations of sizeable packages such as Cython and Django.
Note that only the installation itself is tested, not the packages themselves.
If you would rather install to a different directory, you can add the make parameter PREFIX=/path/to/pyrun/, This will cause make to install eGenix PyRun in /path/to/pyrun/.
If you want to build against a specific Python version, you can specify
the version using the make parameter PYTHONFULLVERSION=2.7.3. Please have a look
PyRun/Makefile for more
ways of customizing the setup.
For future versions of eGenix PyRun, we plan to make the setup customizable via a top-level setup.py file so you can use Python to trigger the build, customize the included standard lib extension modules and installation.
Here's a short session installing setuptools in an eGenix PyRun installation.
First, we install a PyRun version for 32-bit Linux:
tar xvfz egenix-pyrun-1.0.0-py2.7_ucs2.linux-i686.tgz
Now we have a ready to use Python runtime in tmp/, using the default eGenix PyRun directory layout, including some optional extra shared libraries and the include files needed for compiling Python C extensions.
Now, we install setuptools into this runtime:
../bin/pyrun2.7 setup.py install
rm -rf setuptools-0.6c11
Installing pip is just as easy:
../bin/pyrun2.7 setup.py install
rm -rf pip-1.1
You can then install other Python packages using the usual installation methods:
bin/pip install egenix-mx-base
and the packages are available to eGenix PyRun just as they would in a regular Python installation:
pyrun 2.7.3 (default, Jun 24 2012, 20:37:17)
[GCC 4.2.1 (SUSE Linux)]
Thank you for using eGenix PyRun. Type "help" or "license" for details.
