I recommend pip instead of easy_install because it allows you to easily uninstall. First install distribute: http://python-distribute.org/distribute_setup.py Next install pip: https://raw.github.com/pypa/pip/master/contrib/get-pip.py Quickstart guide: http://www.pip-installer.org/en/1.3.1/quickstart.html On Windows, pip and easy_install are a bit limited. I gather that the new Wheel package format (.whl) and compatibility tags should solve the problem (see PEPs 427 and 425). The development version of pip supports Wheel. As is, pip works just fine for installing pure Python packages from source. easy_install also supports binary eggs, but I dislike not having an easy way to uninstall. At least an exe/msi installer lets you uninstall using the Windows control panel. If you have a supported C compiler configured, you can use pip to install packages that have self-contained C extensions (i.e. no dependencies -- such as psutil or cython). Visual Studio [Express] is recommended (2008 for 2.6-3.2; 2010 for 3.3), especially if C++ is used, but MinGW-w64 can be made to work. The big problem here is Windows lacks dependency management for installing libraries and development files (headers and import libs) to known system locations. So compiling an extension module that has dependencies needs to be configured manually. PIL has a lot of dependencies: libjpeg, libtiff, zlib, freetype2, littleCMS, libwebp, and Tcl/Tk. Building it is a moderately challenging process on Windows -- not really suited for a beginner. Building NumPy/SciPy would be even more work since they need a Fortran compiler, too. Fortunately for Windows users, Christoph Gohlke has already done all the hard work for dozens of the most popular packages. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
