[Touch-packages] [Bug 1814653] Re: get_python_lib() returns path to python3 instead of python3.6
The issue is that if `get_python_lib()` is called with `prefix='/usr/local'` argument then Ubuntu version returns: ``` sh $ /usr/bin/python3 -c "from distutils.sysconfig import *;print(get_python_lib(prefix='/usr/local'))" /usr/local/lib/python3/dist-packages ``` while mainstream Python returns: ```sh $ python3 -c "from distutils.sysconfig import *;print(get_python_lib(prefix='/usr/local'))" /usr/local/lib/python3.6/site-packages ``` `sys.path` (in both Ubuntu and mainstream Python) doesn't contain `/usr/local/lib/python3/dist-packages` path, it contains `/usr/local/lib/python3.6/dist-packages` instead, so when `/usr/local` prefix is used things don't work: ``` $ PYTHONPATH='' /usr/bin/python3 -c "import sys; print(sys.path)" ['', '/usr/lib/python36.zip', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', '/home/vital/.local/lib/python3.6/site-packages', '/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages'] ``` -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python3-defaults in Ubuntu. https://bugs.launchpad.net/bugs/1814653 Title: get_python_lib() returns path to python3 instead of python3.6 Status in python3-defaults package in Ubuntu: Confirmed Bug description: Python version is Python 3.6.7 (default, Oct 22 2018, 11:32:17) Ubuntu 18.04.01 When I call get_python_lib() function to get the Python lib path to install a module it returns '/usr/lib/python3/dist-packages' instead of python3.6 dir: python3 -c "from distutils.sysconfig import *;print(get_python_lib())" This is because the source code '/usr/lib/python3.6/distutils/sysconfig.py' has the branch on Ubuntu: Code: if os.name == "posix": libpython = os.path.join(prefix, "lib", "python" + get_python_version()) if standard_lib: return libpython elif (is_default_prefix and 'PYTHONUSERBASE' not in os.environ and 'VIRTUAL_ENV' not in os.environ and 'real_prefix' not in sys.__dict__ and sys.prefix == sys.base_prefix): return os.path.join(prefix, "lib", "python3", "dist-packages") However, this code does not present in the original cpython code 3.6.7: https://github.com/python/cpython/blob/ca7d2933a388677cc3bbc621913b479452c0f25a/Lib/distutils/sysconfig.py#L109 Is it the right behavior?
