Stable Releases
Go to downloads for source distributions for Linux, Unix, Mac OS X and binaries for Windows.
Note that most major *nix distributions now include IPython in their package systems (Ubuntu, Debian, Fedora, SUSE, fink, FreeBSD, OpenBSD,...). Here are links to the various packages, but some of these may lag behind the releases here:
Installation Instructions
To install IPython from source on Linux/Unix/Mac OS X, the following should work:
tar -xvzf ipython-0.7.3.tar.gz cd ipython-0.7.3 python setup.py build sudo python setup.py install
Mac OS X
Depending on which Python you are using on Mac OS X, you may need to install the top level ipython script using the command:
python setup.py install_scripts --install-dir=/usr/local/bin
If you want GUI support in IPython on Mac OS X, you need to make sure that the python called at the top of the ipython script is pythonw.
Please note that on Leopard, there are some extra issues related to the version of Python and readline that Apple ships. This page has more details, and if you are an OSX expert, by all means please add your contributions.
Windows
IPython works well under Windows XP/2k/98/ME and we suspect NT should behave similarly.
On Windows, use the provided ipython-XXX.win32.exe binary installer, which you can simply double-click. You can later uninstall IPython through Settings/Control Panel/Add or Remove Programs. Note that for Windows usage, you need pywin32, ctypes and readline. See this section of the manual for details and links.
CygWin
IPython works mostly OK, though some users have reported problems with prompt coloring. No satisfactory solution to this has been found so far, you may want to disable colors permanently in the ipythonrc configuration file if you experience problems. If you have proper color support under cygwin, please post to the IPython mailing list so this issue can be resolved for all users.
Development Releases
For information about obtaining our development versions of IPython or IPython1, see our Developer Zone wiki page.
