Hi, On a OS/X 101.10.5 (Yosemite) system, the system Python just got updated to 2.7.10 but it sys.path is partially invalid. How can I fix that? I don't want to add something in PYTHONPATH. I know I can create a softlink at the invalid location to where the real files are located. I just want to understand why that sys.path[6] (see below) is invalid and fix it to point to the valid directory. Details follow:
I am running Python 2.7.10: [~]$ python Python 2.7.10 (default, Jul 14 2015, 19:46:27) [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> First, see when I get the sys.path before site.py is imported:: [~]$ python -S -c "import sys, pprint; print sys.prefix; pprint.pprint(sys.path)" /usr ['', '/usr/lib/python27.zip', '/usr/lib/python2.7/', '/usr/lib/python2.7/plat-darwin', '/usr/lib/python2.7/plat-mac', '/usr/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/lib/python2.7/../../Extras/lib/python', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload'] [~]$ python -c "import sys, pprint; print sys.prefix; pprint.pprint(sys.path)" /usr ['', '/usr/lib/python27.zip', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-darwin', '/usr/lib/python2.7/plat-mac', '/usr/lib/python2.7/plat-mac/lib-scriptpackages', '/usr/Extras/lib/python', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/Library/Python/2.7/site-packages'] [~]$ Notice sys.path[6]. It is '/usr/lib/python2.7/../../Extras/lib/python', which when going through site gets normalized to '/usr/Extras/lib/python'. That directory is invalid on my system. It should either be: - The real location: /System/Library/Frameworks/Python.frameworks/Versions/2.7/Extras/lib/python or - the corresponding softlink to that: /usr/lib/python2.7/Extras/lib/python Also note that the sys.prefix is "/usr" I think it should be "/usr/lib/python2.7" or "/System/Library/Frameworks/Python.framework/Versions/2.7" Other Python installed on that system include Python 3.5 (installed via the Python 3.5 DMG installer) and Python 2.7.9 installed with homebrew. For these versions of Python I see something that matches the content of the system storage: - Python 3.5: sys.prefix = '/Library/Frameworks/Python.framework/Versions/3.5' - Python 2.7.9: sys.prefix = '/usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7' Does anyone know how to fix the path generated in sys.path without adding the real directory path in PYTHONPATH?
