Installing Python Modules — Python 2. This document describes the Python Distribution Utilities (“Distutils”) from the. Python installation by building and installing third- party Python. Introduction¶Although Python’s extensive standard library covers many programming needs. Python installation in the form of third- party modules.
This might be necessary. Python. In the past, there has been little support for adding third- party modules to an. Python installation.
With the introduction of the Python Distribution. Utilities (Distutils for short) in Python 2. This document is aimed primarily at the people who need to install third- party. Python modules: end- users and system administrators who just need to get some. Python application running, and existing Python programmers who want to add some.

You don’t need to know Python to read this. Python’s interactive mode.
If you’re looking for information. Python modules so that others may use them, see. Distributing Python Modules manual. Debugging the setup script may also be of.
Best case: trivial installation¶In the best case, someone will have prepared a special version of the module. For example. the module developer might make an executable installer available for Windows.
RPM package for users of RPM- based Linux systems (Red Hat, Su. SE. Mandrake, and many others), a Debian package for users of Debian- based Linux. In that case, you would download the installer appropriate to your platform and. RPM, etc. You don’t need to run Python or a setup. Of course, things will not always be that easy. You might be interested in a.
In that case, you’ll have to start with the source distribution. Installing from a source. The bulk of this document is about building and installing. The new standard: Distutils¶If you download a module source distribution, you can tell pretty quickly if it. Distutils. First, the distribution’s name and version number will be featured prominently.
Next, the archive will unpack into a similarly- named. Additionally, the.
README. txt or possibly just README, which should explain that. For Windows, this command should be run from a command prompt window. If all these things are true, then you already know how to build and install the. Run the command above. Unless you need to.
Or rather, the above command is everything you need to. Standard Build and Install¶As described in section The new standard: Distutils, building and installing a module. Distutils is usually one simple command to run from a. Platform variations¶You should always run the setup command from the distribution root directory. For example, if you’ve just downloaded a module source distribution. Unix system, the normal thing to do is: gunzip - c foo- 1.
On Windows, you’d probably download foo- 1. If you downloaded the. C: \Temp, then it would unpack into. C: \Temp\foo- 1. 0; you can use either an archive manipulator with a.
Win. Zip) or a command- line tool (such as. Then, open a. command prompt window and run: cd c: \Temp\foo- 1. Splitting the job up¶Running setup. If you. prefer to work incrementally—especially useful if you want to customize the.
This is particularly helpful when the build and install. For example, you can build everything in one step, and then install everything. If you do this, you will notice that running the install command. You may not need this ability to break things down often if all you do is. If you get into distributing your own Python modules and extensions. Distutils commands on their own.
How building works¶As implied above, the build command is responsible for putting the. By default, this is build. For example: python setup. Or you could do this permanently with a directive in your system or personal. Distutils configuration file; see section Distutils Configuration Files.) Normally, this. The default layout for the build tree is as follows: -- - build/ - -- lib/. OS/hardware. platform and Python version.
The first form, with just a lib directory. Python modules. If a module distribution contains any. C/C++), then the second form, with two < plat>. In that case, the temp. In either case, the lib (or lib.
Python modules (pure Python and extensions) that will be installed. In the future, more directories will be added to handle Python scripts. Python modules and applications. How installation works¶After the build command runs (whether you run it explicitly, or the. If you don’t choose an installation directory—i. Python modules. This location varies by platform and.
Python itself. On Unix (and Mac OS X, which is also. Unix- based), it also depends on whether the module distribution being installed. Python or contains extensions (“non- pure”): Platform. Standard installation location. Default value. Notes. Unix (pure)prefix/lib/python.

If you build Python yourself on Linux (or any Unix- like system), the.
The default installation directory on Windows was C: \Program. Files\Python under Python 1. Python. is installed to, and where it finds its libraries at run- time.
They are always. the same under Windows, and very often the same under Unix and Mac OS X. You. can find out what your Python installation uses for prefix and. Python in interactive mode and typing a few. Under Unix, just type python at the shell prompt. Under. Windows, choose . Once the interpreter is started, you type Python code. For example, on my Linux system, I type the three Python.

Alternate Installation¶Often, it is necessary or desirable to install modules to a location other than. Python modules. For example, on a Unix. Or you might wish to try out a module before making it a standard. Python installation.
This is especially true when upgrading. The Distutils install command is designed to make installing module. The basic idea is.
The details. differ across platforms, so read whichever of the following sections applies to. Note that the various alternate installation schemes are mutually exclusive: you. Alternate installation: the user scheme¶This scheme is designed to be the most convenient solution for users that don’t. It is enabled with a simple option: python setup.
Files will be installed into subdirectories of site. USER_BASE (written. This scheme installs pure Python modules and. USER_SITE). Here are the values for UNIX, including Mac OS X: Type of file. Installation directorymodulesuserbase/lib/python. X. Y/site- packagesscriptsuserbase/bindatauserbase. C headersuserbase/include/python.
X. Y/distname. And here are the values used on Windows: Type of file. Installation directorymodulesuserbase\Python. XY\site- packagesscriptsuserbase\Scriptsdatauserbase.
C headersuserbase\Python. XY\Include\distname. The advantage of using this scheme compared to the other ones described below is. The build_ext command also has a - -user option to add. C libraries (rpath).
Alternate installation: the home scheme¶The idea behind the “home scheme” is that you build and maintain a personal. Python modules. This scheme’s name is derived from the idea of a. Unix, since it’s not unusual for a Unix user to make their.
This scheme can be used by anyone, regardless of the operating system they. Installing a new module distribution is as simple aspython setup. On. Unix, lazy typists can just type a tilde (~); the install command. To make Python find the distributions installed with this scheme, you may have.
Python’s search path or edit. The - -home option defines the installation base directory. Files are. installed to the following directories under the installation base as follows: Type of file.
Installation directorymoduleshome/lib/pythonscriptshome/bindatahome. C headershome/include/python/distname(Mentally replace slashes with backslashes if you’re on Windows.)Changed in version 2. The - -home option used to be supported only on Unix. Alternate installation: Unix (the prefix scheme)¶The “prefix scheme” is useful when you wish to use one Python installation to. Python installation (or. Python installation). If this sounds a.
However. there are at least two known cases where the prefix scheme will be useful. First, consider that many Linux distributions put Python in /usr, rather. This is entirely appropriate. Python is part of “the system” rather than a local add- on. However, if you are installing Python modules from source, you probably want. X rather than. /usr/lib/python. X. This can be done with/usr/bin/python setup.
Another possibility is a network filesystem where the name used to write to a. Python interpreter accessed as /usr/local/bin/python might search for. X, but those modules would have to. X. This could. be done with/usr/local/bin/python setup. In either case, the - -prefix option defines the installation base, and. Currently, this just means. C libraries, binary.
If - -exec- prefix is not supplied, it defaults to. Files are installed as follows: Type of file. Installation directory.
Python modulesprefix/lib/python. X. Y/site- packagesextension modulesexec- prefix/lib/python. X. Y/site- packagesscriptsprefix/bindataprefix.
C headersprefix/include/python. X. Y/distname. There is no requirement that - -prefix or - -exec- prefix. Python installation; if the directories listed.
Incidentally, the real reason the prefix scheme is important is simply that a. Unix installation uses the prefix scheme, but with - -prefix.
Python itself as sys. Thus, you might think you’ll never use the prefix scheme.
