I recently installed a package using python setup.py --single-version-externally-managed --record record.txt option. In my site-packaged folder, there is now two new folders and a file. <top-of-package-namespace>/ <package>-<version>.egg-info/ <package>-<version>-nspkg.pth Now when I start up python, I get the message 'import site' failed; use -v for traceback When I do python -v, I get the following traceback: # installing zipimport hook import zipimport # builtin # installed zipimport hook # /usr/lib/python2.5/site.pyc matches /usr/lib/python2.5/site.py import site # precompiled from /usr/lib/python2.5/site.pyc # /usr/lib/python2.5/os.pyc matches /usr/lib/python2.5/os.py import os # precompiled from /usr/lib/python2.5/os.pyc import posix # builtin # /usr/lib/python2.5/posixpath.pyc matches /usr/lib/python2.5/posixpath.py import posixpath # precompiled from /usr/lib/python2.5/posixpath.pyc # /usr/lib/python2.5/stat.pyc matches /usr/lib/python2.5/stat.py import stat # precompiled from /usr/lib/python2.5/stat.pyc # /usr/lib/python2.5/UserDict.pyc matches /usr/lib/python2.5/UserDict.py import UserDict # precompiled from /usr/lib/python2.5/UserDict.pyc # /usr/lib/python2.5/copy_reg.pyc matches /usr/lib/python2.5/copy_reg.py import copy_reg # precompiled from /usr/lib/python2.5/copy_reg.pyc # /usr/lib/python2.5/types.pyc matches /usr/lib/python2.5/types.py import types # precompiled from /usr/lib/python2.5/types.pyc import _types # builtin # zipimport: found 78 names in /usr/lib/python2.5/site-packages/setuptools-0.6c8-py2.5.egg # /usr/lib/python2.5/new.pyc matches /usr/lib/python2.5/new.py import new # precompiled from /usr/lib/python2.5/new.pyc 'import site' failed; traceback: Traceback (most recent call last): File "/usr/lib/python2.5/site.py", line 415, in <module> main() File "/usr/lib/python2.5/site.py", line 400, in main paths_in_sys = addsitepackages(paths_in_sys) File "/usr/lib/python2.5/site.py", line 206, in addsitepackages addsitedir(sitedir, known_paths) File "/usr/lib/python2.5/site.py", line 169, in addsitedir addpackage(sitedir, name, known_paths) File "/usr/lib/python2.5/site.py", line 138, in addpackage exec line File "<string>", line 1, in <module> KeyError: 'enthought' # /usr/lib/python2.5/warnings.pyc matches /usr/lib/python2.5/warnings.py import warnings # precompiled from /usr/lib/python2.5/warnings.pyc # /usr/lib/python2.5/linecache.pyc matches /usr/lib/python2.5/linecache.py import linecache # precompiled from /usr/lib/python2.5/linecache.pyc import encodings # directory /usr/lib/python2.5/encodings # /usr/lib/python2.5/encodings/__init__.pyc matches /usr/lib/python2.5/encodings/__init__.py import encodings # precompiled from /usr/lib/python2.5/encodings/__init__.pyc # /usr/lib/python2.5/codecs.pyc matches /usr/lib/python2.5/codecs.py import codecs # precompiled from /usr/lib/python2.5/codecs.pyc import _codecs # builtin # /usr/lib/python2.5/encodings/aliases.pyc matches /usr/lib/python2.5/encodings/aliases.py import encodings.aliases # precompiled from /usr/lib/python2.5/encodings/aliases.pyc # /usr/lib/python2.5/encodings/ascii.pyc matches /usr/lib/python2.5/encodings/ascii.py import encodings.ascii # precompiled from /usr/lib/python2.5/encodings/ascii.pyc Python 2.5.1 (r251:54863, Jan 10 2008, 18:01:57) [GCC 4.2.1 (SUSE Linux)] on linux2 Type "help", "copyright", "credits" or "license" for more information. dlopen("/usr/lib/python2.5/lib-dynload/readline.so", 2); import readline # dynamically loaded from /usr/lib/python2.5/lib-dynload/readline.so # /usr/lib/python2.5/atexit.pyc matches /usr/lib/python2.5/atexit.py import atexit # precompiled from /usr/lib/python2.5/atexit.pyc # /usr/lib/python2.5/rlcompleter.pyc matches /usr/lib/python2.5/rlcompleter.py import rlcompleter # precompiled from /usr/lib/python2.5/rlcompleter.pyc
