I've pushed the change to revert Issue4865 for the 2.7 branch for release with 2.7.13. Issue #28440: No longer add /Library/Python/site-packages, the Apple-supplied New changeset a8a342b3fbc7 by Ned Deily in branch '2.7': I'm a bit sad that this feature has to go, but modern Python use (in particular virtualenv) has reduced the need for this feature. It's currently only an issue for 2.7.x since Apple has not yet shipped versions of Python 3.x but the code should be removed there, too.Īuthor: Ronald Oussoren (ronaldoussoren) *Īnother reason to remove this feature: installing python 2.7.12 using the installer on breaks the system install of Python, likely because of this issue.

I think experience has shown this was not a good idea because of the coupling it introduced between separate Python installations and some third-party distributors of Python on OS X already patch this code out. The behavior of adding the system Python's site-packages directory to the search path of all framework-build Pythons was deliberately added as a result of Issue4865.

This also affects the -m ensurepip installation of pip itself: the pip install fails trying to upgrade the Apple-supplied version of setuptools. I am attaching a patch that removes the block of code in site.py which adds these paths. 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. The effect of including this SIP-protected path in sys.path is this: installing or upgrade a package in /Library/Frameworks/amework which is also installed as an "Extra" in the /System/Frameworks/amework 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. The latter directory (which is protected by SIP) contains many Python 2.7 packages, including easy_install, setuptools, six, py2app, numpy, pylab and pyOpenSSL. System/Library/Frameworks/amework/Versions/2.7/Extras/lib/python pth file, which results in sys.path containing the path: The current version of site.py reads that. Library/Python/2.7/site-packages/Extras.pth The new file that causes the problem on Sierra is:
FilesĬhanges made to /Library/Python on macOSX Sierra cause the -with-ensurepip compiler flag to fail, and lead to failures of pip after installing Python.

Please migrate to Python 3.Ensurepip and pip install failures on macOS Sierra with non-system Python 2.7.x Note: pip 21.0, in January 2021, removed Python 2 support, per pip’s Python 2 support policy. We want your input, so sign up for our user experience research studies to help us do it right. In pip 20.3, we’ve made a big improvement to the heart of pip learn more. We release updates regularly, with a new version every 3 months.

Please take a look at our documentation for how to install and use pip: You can use pip to install packages from the Python Package Index and other indexes.
