New submission from Marc Culler: Changes made to /Library/Python on macOSX Sierra cause the --with-ensurepip compiler flag to fail, and lead to failures of pip after installing Python.
The new file that causes the problem on Sierra is: /Library/Python/2.7/site-packages/Extras.pth The current version of site.py reads that .pth file, which results in sys.path containing the path: /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python The latter directory (which is protected by SIP) contains many Python 2.7 packages, including easy_install, setuptools, six, py2app, numpy, pylab and pyOpenSSL. The effect of including this SIP-protected path in sys.path is this: installing or upgrade a package in /Library/Frameworks/Python.framework which is also installed as an "Extra" in the /System/Frameworks/Python.framework will cause pip to attempt to delete the "old" package from its SIP-protected directory, leading to a "Permission Denied" exception and a failed install. Given that Apple has now tied /Library/Python to the system Python in this way, thereby making a separate Python framework in /Library/Frameworks unusable, the natural solution to this problem would be to stop including any /Library/Python paths in sys.path. I am attaching a patch that removes the block of code in site.py which adds these paths. ---------- files: pipfails.patch keywords: patch messages: 278649 nosy: Marc.Culler priority: normal severity: normal status: open title: pip failures on macOS Sierra type: compile error Added file: http://bugs.python.org/file45090/pipfails.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28440> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
