[Qgis-user] Python challenges under OS X Lion

[William Kyngesburye]

Well, there's QGIS plugins and Python modules.  And there's different Python versions.

Easy_install works with python modules, and some modules may include compiled coded needing Xcode, and others may be pure python, no Xcode needed.  QGIS itself handles QGIS plugins, no Xcode needed.

QGIS plugins may need python modules to work.

So, for QGIS 1.7 in Lion, it's a bit of a problem because the Snow Leopard package runs on Lion just fine, but uses the System Python 2.6.  If there are any Python modules needed by QGIS plugins, those modules must be installed for Python 2.6 for QGIS plugins to see them.  easy_install will install for Python 2.7 (it may be possible to install for 2.6).

I haven't rebuilt QGIS 1.7 for Lion.  At first I thought 1.7.1 was imminent, but that was stalled, then Qt needed an update for Lion, now I'm just lazy and waiting for 1.7.1 still.

If you're willing to work on the edge, my QGIS dev build is made for Lion and the system Python 2.7, so you can easy_install any Python modules needed.  Or install my Python modules where available (ie psycopg2).

I went to start reinstalling some of the plugins.  As I expected, the python plugins were no longer there.  I went into terminal and used the easyinstall command.  It didn't work.  I read somewhere about needing Xtools, so I downloaded those for free from the app store.  Now terminal claims to have installed them (I did get some warning messages) but Qgis can't find them when I go to install the plugins.

All generalizations are dangerous, even this one.
