[IPython-dev] Twisted 8...
Mon Mar 31 20:18:35 CDT 2008
Being installable via easy_install is a huge win (really a
requirement) on OS X 10.5. Leopard comes with a system Twisted 2.4 and
installing a newer version (such as the 2.5 required by ipython1)
requires mucking with the PYTHONPATH (not a mac user-friendly task).
Even worse, PYTHONPATH changes are not propagated via sudo (for
obvious reasons), so running code that requires twisted 2.5 as root is
impossible, even with the PYTHONPATH modification. Installation via
easy_install fixes these issues (the easy_install'd Twisted is placed
before the system Twisted on the sys.path by setuptools). With
setuptools/easy_install support, it's possible to automate deployment
of pre-compiled eggs.
There's currently a branch of Twisted 2.5 that is installable via
setuptools/easy_install, but the official release isn't.
So, making Twisted and ipython1 a reality of OS X will require
setuptools/easy_install support. So, +1 from OS X land.
