I am also seeing this in my Mac Mavericks Python 3 installation when I use just the built-in logging library. Again, a tiny example executable script and the results:
$ cat test2.py #!/usr/bin/env python3 import logging logging.info("TEST2 starting") $ ./test2.py Traceback (most recent call last): File "./test2.py", line 3, in <module> import logging File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/logging/__init__.py", line 26, in <module> import sys, os, time, io, traceback, warnings, weakref, collections File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/traceback.py", line 3, in <module> import linecache File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/linecache.py", line 10, in <module> import tokenize File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/tokenize.py", line 40, in <module> __all__ = token.__all__ + ["COMMENT", "tokenize", "detect_encoding", AttributeError: 'module' object has no attribute '__all__' Googling hasn't helped track this one down. In lieu of an answer, some pointers to tools or other things to look for would be greatly appreciated. Thanks! Brian -- https://mail.python.org/mailman/listinfo/python-list
