Newbie: Runtime error when importing arcpy

stephaniemay — Wed, 06 Jul 2011 21:02:28 GMT

Hi all,

Running ArcGIS 10.0, ArcView license, Windows 7

I am taking an initial stab at using arcpy in ArcGIS 10.0... but so far I can't get out of the gates. when I type "import arcpy" at the command line of the Python window, I get:

Runtime error <type 'exceptions.TypeError'>: cannot create weak reference to 'classobj' object

Other possibly relevant info:
- I installed Python 2.7.2 recently, completely separate from the 2.6 installation, to practice using Python outside of ArcGIS. I thought the paths might be messed up but none of my machine's environment variables make reference to either installation (under System Properties).
- arcpy exists at C:\Program Files\ArcGIS\Desktop10.0\arcpy

Any help appreciated.
S.

If you are Newbie...don't mess with mother nature...ArcMap requires a certain version of Python installed in a certain path...so uninstall the latest and greatest version of Python (which doesn't add anything you are going to need for a long time) and stick with what ArcMap requires. When you become post-newbie, then there are lots of threads on how to temp fate with other versions and installation priorities and the like.

Ok, uninstalling 2.7.2 did indeed solve it. ArcGIS crashed two more times and imports arcpy just fine now. Thank you, although I am not sure "mother nature" has anything to do with it.
