In the past, as far as I know, it’s never tried to have anything to do with /System. Again, I don’t know if it’s something about macOS 10.12 Sierra, or my particular setup that is the problem. Also, to be clear, there are no PYTHON* or other environment variables that would affect the python path. Here is a failing session… (Aside: I understand that "pyobjc-framework-Message” is actually a bad example: it is the only package that even —-ignore-installed actually fails on, because it has the "--single-version-externally-managed” problem which is a different kettle of fish. But I think the above error message is the same as the one that I would get for any of the other packages in question. Note that pip2 install works fine for packages other than those in my original list.) $ command which pip2 /Library/Frameworks/Python.framework/Versions/2.7/bin/pip2 $ pip2 install --upgrade pyobjc-framework-Message Collecting pyobjc-framework-Message Using cached pyobjc-framework-Message-3.1.1.tar.gz Requirement already up-to-date: pyobjc-core>=3.1.1 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from pyobjc-framework-Message) Requirement already up-to-date: pyobjc-framework-Cocoa>=3.1.1 in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (from pyobjc-framework-Message) Installing collected packages: pyobjc-framework-Message Found existing installation: pyobjc-framework-Message 2.5.1 Uninstalling pyobjc-framework-Message-2.5.1: Exception: Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/basecommand.py", line 215, in main status = self.run(options, args) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/commands/install.py", line 317, in run prefix=options.prefix_path, File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/req/req_set.py", line 736, in install requirement.uninstall(auto_confirm=True) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/req/req_install.py", line 742, in uninstall paths_to_remove.remove(auto_confirm) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/req/req_uninstall.py", line 115, in remove renames(path, new_path) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip/utils/__init__.py", line 267, in renames shutil.move(old, new) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 299, in move copytree(src, real_dst, symlinks=True) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/shutil.py", line 208, in copytree raise Error, errors Error: [('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/__init__.py', '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/__init__.py', "[Errno 1] Operation not permitted: '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/__init__.py'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/__init__.pyc', '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/__init__.pyc', "[Errno 1] Operation not permitted: '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/__init__.pyc'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/_metadata.py', '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/_metadata.py', "[Errno 1] Operation not permitted: '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/_metadata.py'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/_metadata.pyc', '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/_metadata.pyc', "[Errno 1] Operation not permitted: '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message/_metadata.pyc'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message', '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message', "[Errno 1] Operation not permitted: '/var/folders/bk/zdhpxqj14y5fzcvlpybb4b640000gn/T/pip-Gd3OiE-uninstall/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC/Message'”)]
