Daniel, Any time you see the "import site failed" error from Python, you can infer that there is a problem with the Python interpreter being unable to access its required libraries. Messages after that aren't typically informative.
This usually a path configuration issue, but I think it can also happen when there is a version mismatch betweehn the executable the libraries (running python 2.5 executables against 2.4 libraries or vice versa). If using the system-provided Python, you shouldn't have to set PYTHON_HOME since it will have been compiled in by default. Try the following in a new shell: export PYMOL_PATH=/var/lib/python-support/python2.5/pymol/ python2.5 ${PYMOL_PATH}/__init__.py Cheers, Warren -- DeLano Scientific LLC Subscriber Support Services mailto:supp...@delsci.com -----Original Message----- From: pymol-users-boun...@lists.sourceforge.net [mailto:pymol-users-boun...@lists.sourceforge.net] On Behalf Of Daniel Rigden Sent: Tuesday, July 22, 2008 7:39 AM To: pymol-users@lists.sourceforge.net Subject: [PyMOL] python/pymol malfunction on new Ubuntu installation Dear all First let me confess that my problem does not just involved pymol. However, it is hampering my use of pymol amongst other things and there must be many python experts who read this list. My problem, on a completely fresh Ubuntu 8.04 install, is that python can find modules when asked to import them. So export PYMOL_PATH=/var/lib/python-support/python2.5/pymol/ export PYTHONHOME=/usr/lib/python2.5 python2.5 ${PYMOL_PATH}/__init__.py gives me 'import site' failed; use -v for traceback Traceback (most recent call last): File "/var/lib/python-support/python2.5/pymol//__init__.py", line 109, in <module> import threading ImportError: No module named threading /usr/lib/python2.5 contains site.py, threading.py and all the rest. Can anyone help? I'd be very grateful.
