Ned Deily added the comment: FWIW, works for me using the python.org 3.4 64-bin installer. What is the output of:
python3 -c 'import sys;print(sys.version)' As Claudiu suggests, check for a concurrent.py shadowing the standard library version. Also, why are you setting PYTHONPATH to include /Library/Frameworks/Python.framework/Versions/{3.4,2.7}/lib/python3.4/site-packages/? Those are the standard locations for site-packages are included automatically in sys.path by the respective interpreters. Setting PYTHONPATH should not normally be needed. ---------- nosy: +ned.deily _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21378> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
