Sympy has some installation problems. 1. Depenencies. Sympy depends on pyglet and mpmath and they are thus included in a separate thirdparty directory. This has some drawbacks: Other programs than sympy can't use them and it ignores existing installations of these modules. Furthermore it's involved in issues like the following one.
2. Upgrading. The current, distutils-based setup.py doesn't remove old files before installing, which can break sympy completely: http://code.google.com/p/sympy/issues/detail?id=864 I think at least the first problem can be solved when using setuptools/ easy_install instead of distutils, as one of the main advantages of setuptools is dependencies-handling. The second problem can probably be solved too (there seems to be support for upgrading/uninstalling), but I'm not sure. I just tried easy_install for ipython: " # easy_install ipython Searching for ipython Reading http://pypi.python.org/simple/ipython/ Reading http://ipython.scipy.org Reading http://ipython.scipy.org/dist Best match: ipython 0.8.4 Downloading http://ipython.scipy.org/dist/ipython-0.8.4-py2.5.egg Processing ipython-0.8.4-py2.5.egg creating /usr/local/lib/python2.5/site-packages/ipython-0.8.4- py2.5.egg Extracting ipython-0.8.4-py2.5.egg to /usr/local/lib/python2.5/site- packages Adding ipython 0.8.4 to easy-install.pth file Installing ipython script to /usr/local/bin Installing pycolor script to /usr/local/bin Installed /usr/local/lib/python2.5/site-packages/ipython-0.8.4- py2.5.egg Processing dependencies for ipython Finished processing dependencies for ipython " IMHO it's awesome. Let's switch to this way of distribution of sympy and its third party modules. (Additionally there could be of course a tar ball with all dependencies included.) What do you think?
