I tried to upgrade pip with:
pip install –upgrade setuptools pip wheel
and got the following error:
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
ERROR: Invalid requirement: '\xe2\x80\x93upgrade'
After doing:
sudo pip install --upgrade setuptools pip wheel
I get the following error:
ERROR: Could not install packages due to an EnvironmentError: [('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/_markerlib/markers.pyc', '/private/tmp/pip-uninstall-MzJySA/markers.pyc', "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-MzJySA/markers.pyc'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/_markerlib/init.py', '/private/tmp/pip-uninstall-MzJySA/init.py', "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-MzJySA/init.py'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/_markerlib/markers.py', '/private/tmp/pip-uninstall-MzJySA/markers.py', "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-MzJySA/markers.py'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/_markerlib/init.pyc', '/private/tmp/pip-uninstall-MzJySA/init.pyc', "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-MzJySA/init.pyc'"), ('/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/_markerlib', '/private/tmp/pip-uninstall-MzJySA', "[Errno 1] Operation not permitted: '/private/tmp/pip-uninstall-MzJySA'")]
How can I fix that on OSX?
\xe2\x80\x93
is the UTF-8 encoding of the Unicode character EN DASH U+2013 which is entirely distinct from (though vaguely visually similar to) the double ASCII minus character which commonly indicates an option name.
You want --upgrade
, not –upgrade
.
Sometimes e.g. blog platforms "helpfully" replace ASCII sequences like dashes, quotes, etc with "typographic" HTML equivalents which are more pleasing to the eye, but such substitutions should never be performed in code
spans.
On MacOS, I would seriously caution against trying to upgrade the system-supplied files; sometimes, they are pinned to an older version for very good reasons, and regardless of that, you will be jeopardizing your ability to install future OS upgrades correctly if you muck with system files. Instead, try to use an isolated environment where you can upgrade individual libraries without touching the ones supplied by the system - the venv
package installed with Python 3 is the baseline solution, but there are alternatives like the third-party virtualenv
package (if you are really still stuck on Python 2! With condolences), pyenv
, miniconda
etc.
Try running:
pip install --upgrade setuptools pip wheel
With double --
