You will need Python version 2.6 or better to runPyramid.
Pyramid is known to run on all popular UNIX-like systems such as Linux,Mac OS X, and FreeBSD as well as on Windows platforms. It is also known to runon PyPy (1.9+).
Pyramid installation does not require the compilation of any C code, soyou need only a Python interpreter that meets the requirements mentioned.
Some Pyramid dependencies may attempt to build C extensions forperformance speedups. If a compiler or Python headers are unavailable thedependency will fall back to using pure Python instead.
For Mac OS X Users¶
Python comes pre-installed on Mac OS X, but due to Apple's release cycle, it isoften out of date. Unless you have a need for a specific earlier version, it isrecommended to install the latest 2.x or 3.x version of Python.
You can install the latest verion of Python for Mac OS X from the binaries onpython.org.
Alternatively, you can use the homebrew package manager.
If you use an installer for your Python, then you can skip to the sectionInstalling Pyramid on a UNIX System.
If You Don't Yet Have a Python Interpreter (UNIX)¶
If your system doesn't have a Python interpreter, and you're on UNIX, you caneither install Python using your operating system's package manager or youcan install Python from source fairly easily on any UNIX system that hasdevelopment tools.
Package Manager Method¶

You can use your system's 'package manager' to install Python. Each packagemanager is slightly different, but the 'flavor' of them is usually the same.
For example, on a Debian or Ubuntu system, use the following command:
This command will install both the Python interpreter and its developmentheader files. Note that the headers are required by some (optional) Cextensions in software depended upon by Pyramid, not by Pyramid itself.
Once these steps are performed, the Python interpreter will usually beinvokable via python2.7 from a shell prompt.
Source Compile Method¶
It's useful to use a Python interpreter that isn't the 'system' Pythoninterpreter to develop your software. The authors of Pyramid tend notto use the system Python for development purposes; always a self-compiled one.Compiling Python is usually easy, and often the 'system' Python is compiledwith options that aren't optimal for web development. For an explanation, seehttps://github.com/Pylons/pyramid/issues/747.
To compile software on your UNIX system, typically you need development tools.Often these can be installed via the package manager. For example, this worksto do so on an Ubuntu Linux system:

On Mac OS X, installing XCode hasmuch the same effect.
Once you've got development tools installed on your system, you can install aPython 2.7 interpreter from source, on the same system, using the followingcommands:
Once these steps are performed, the Python interpreter will be invokable via$HOME/opt/Python-2.7.3/bin/python from a shell prompt.
If You Don't Yet Have a Python Interpreter (Windows)¶
If your Windows system doesn't have a Python interpreter, you'll need toinstall it by downloading a Python 2.7-series interpreter executable frompython.org's download section (the fileslabeled 'Windows Installer'). Once you've downloaded it, double click on theexecutable and accept the defaults during the installation process. You mayalso need to download and install the Python for Windows extensions.
Warning
After you install Python on Windows, you may need to add the C:Python27directory to your environment's Path in order to make it possible toinvoke Python from a command prompt by typing python. To do so, rightclick MyComputer, select Properties --> AdvancedTab -->EnvironmentVariables and add that directory to the end of the Pathenvironment variable.
